CBSE Case Based Questions Class 10 Science Chemistry Chapter 6

CASE STUDY : 1

Carbon and energy requirements of the autotrophic organism are fulfilled by photosynthesis. It is the process by which autotrophs take in substances from the outside and convert them into stored forms of energy. This material is taken in the form of carbon dioxide and water which is converted into carbohydrates in the presence of sunlight and chlorophyll. Carbohydrates are utilised for providing energy to the plant.

i) Write a chemical reaction which occur during photosynthesis?

Ans: 6CO2 +12H2O + Chlorophyll & sunlight👉 C6H12O6 + 6O2 + 6H2O

ii) In which form of carbohydrates does the plant stored in them?

Ans: The carbohydrates are stored in the form of starch as the internal energy.

iii) What is stomata?

Ans: The process present in the surface of a leaf or the stem of a plant to allow the exchange of gases.

iv) What are the functions of stomata?

Ans: i) Exchange of gases i.e oxygen and CO2

ii) Transpiration

v) What is Chloroplast?

Ans: Chloroplast is a cell organelles which contains photosynthetic pigment called as chlorophyll which help in the absorption of sunlight.

CASE STUDY : 2

The alimentary canal is basically a long tube extending from the mouth to the anus. In Fig. 6.6, we can see that the tube has different parts. Various regions are specialised to perform different functions.

We eat various types of food which has to pass through the same digestive tract. Naturally the food has to be processed to generate particles which are small and of the same texture. This is achieved by crushing the food with our teeth

i) Which enzyme is present in our mouth to digest starch?

Ans: Salivary amylase from salivary glands.

ii) What are the types of enzymes released by our stomach?

Ans: Hydrochloric acid, pepsin and a mucus.

iii) Which is the longest part of our alimentary canal in our body?

Ans: Small intestine

iv) What are villi?

Ans: Villi are finger like projection present inside the inner lining of the small intestine which increases the surface area for absorption.

v) What are the enzymes that are released by pancreas?

Ans: Enzyme released by pancreas – • trypsin- Digestion of protein

lipase – breakdown of emulsified fats

CASE STUDY : 3

The food material taken in during the process of nutrition is used in cells to provide energy for various life processes. Diverse organisms do this in different ways – some use oxygen to break-down glucose completely into carbon dioxide and water, some use other pathways that do not involve oxygen (Fig. 6.8). In all cases, the first step is the break-down of glucose, a six-carbon molecule, into a three-carbon molecule called pyruvate. This process takes place in the cytoplasm.

i) What is anaerobic respiration?

Ans: The conversion of pyruvate into ethanol, CO2 & energy take place in the absence of air(oxygen), it is called anaerobic respiration.

ii) Explain the process which happen in our muscle cells?

Ans- The conversion of pyruvate to lactic acid( 3 carbon molecule) and energy due to the lack of oxygen.

iii) In which form our body used the energy?

Ans: It is in the form of ATP molecule i.e Adenosine Triphosphate.

iv) Why there is a faster breathing rate of aquatic animals then the terrestrial animals?

Ans- The amount of O2 dissolved in water is low as compared to amount of O2 present in air. Therefore, aquatic animals have faster breathing rate.

v) Write the name of organ used for respiration by different organism- fish, frog?

Ans- i) fish- gills

ii) frog- skin, lungs

CASE STUDY : 4

The excretory system of human beings includes a pair of kidneys, a pair of ureters, a urinary bladder and a urethra. Kidneys are located in the abdomen, one on either side of the backbone. Urine produced in the kidneys passes through the ureters into the urinary bladder where it is stored until it is released through the urethra.

i) What is the purpose of making urine?

Ans: Urine is to filter out the blood i e to remove waste product from the blood such as urea.

ii) What is Bowman’s capsule?

Ans: A cup shaped end of a coiled tube which is associated with capillaries to collect filterate.

V) Which device measured blood pressure?

Ans: Sphygmomanometer

CASE STUDY : 6

Plant transport systems will move energy stores from leaves and raw materials from roots. These two pathways are constructed as independently organised conducting tubes. One, the xylem moves water and minerals obtained from the soil. The other, phloem transports products of photosynthesis from the leaves where they are synthesised to other parts of the plant

i) What are the different parts of xylem?

Ans: vessels, tracheids, xylem parenchyma and fibres.

ii) What do you meant by the term transpiration?

Ans: The loss of water in the form of vapour from the aerial parts of the plant.

iii) What are the advantages of transpiration?

Case Study 3: Life processes are the essential functions that living organisms perform to maintain their existence. These processes include nutrition, respiration, transportation, excretion, and reproduction. Nutrition involves the intake of food and its utilization by the body for energy and growth. It can be classified into two types: autotrophic and heterotrophic. Autotrophic nutrition is the process by which organisms, such as plants, produce their own food using sunlight, water, and carbon dioxide through photosynthesis. Heterotrophic nutrition is the process by which organisms obtain nutrients by consuming other organisms. Respiration is the process of releasing energy from food through the oxidation of glucose molecules. Transportation involves the movement of materials, such as nutrients, water, and gases, within the body. Excretion is the removal of waste products generated by metabolic activities. Reproduction is the process by which organisms produce offspring of their own kind. Understanding life processes is crucial for studying the functioning and survival of living organisms.

In human being, the holozoic nutrition takes place in five steps: 1. Ingestion. The process of taking food inside the body is called ingestion. 2. Digestion. In digestion, the ingested food is converted into simple form with the help of digestive enzymes. 3. Absorption. In this stage the food digested in second step is absorbed into the cells of body. 4. Assimilation. Assimilation is the process of utilising the food absorbed in third step by various cells of the body. 5. Egestion. Egestion is the final step of holozoic nutrition in which the undigested food is removed from the body.

Each capillary cluster in the kidney is associated with the cup-shaped end of a tube that collects the filtered urine (see adjoining figure). Each kidney has large numbers of these filtration units called nephrons packed close together. Some substances in the initial filtrate, such as glucose, amino acids, salts and a major amount of water, are selectively re-absorbed as the urine flows along the tube. The amount of water reabsorbed depends on how much excess water there is in the body, and on how much of dissolved waste there is to be excreted. The urine forming in each kidney eventually enters a long tube, the ureter, which connects the kidneys with the urinary bladder. Urine is stored in the urinary bladder until the pressure of the expanded bladder leads to the urge to pass it out through the urethra. The bladder is muscular, so it is under nervous control, as we have discussed elsewhere. As a result, we can usually control the urge to urinate.

Question. The substance which is not reabsorbed into the blood capillaries surrounding the tubule of a nephron is mainly: (a) glucose (b) amino acid (c) urea (d) water

Water is very important chemical, required as solvent, in many biological processes. It is needed as raw material in photosynthesis, as a main substance from which plants evolve oxygen and provide hydrogen for the synthesis of carbohydrates. It helps in translocation of chemical substances and minerals and in this manner maintains internal transportation. Osmosis is a special type of transport of water molecules that occurs through semipermeable membrane. Osmosis is movement of solvent from the region of higher diffusion pressure to the lower diffusion pressure across a semipermeable membrane. It is of two types - endosmosis and exosmosis. Endosmosis is the osmotic entry of water into a cell, organ or system. Exosmosis is the osmotic withdrawal of water from a cell, organ or system.

Our body needs to remove the wastes that build up from cell activities and from digestion. It these wastes are not removed, then our cells can stop working and we can get very sick. The organs of our excretory system help to release wastes from our body. The excretory system consists of a pair of kidney, a pair of ureters, a urinary bladder and a urethra. Each kidney is made up of nearly one million complex tubular structures called nephrons. The formation of urine involves various processes that takes place in the different parts of the nephron. Each nephron consists of a cup-shaped upper end called Bowman's capsule containing a bunch of capillaries called glomerulus. Bowman's capsule leads to tubular structure-proximal convoluted tubule, loop of Henle and distal convoluted tubule which ultimately joins the collecting tubule. (i) The following substances are the excretory products in animals. Choose the least toxic form.

Life processes case study questions with answer key answer keys.

(i) (a): In human, cellulose is indigestible as it cannot be broken into smaller molecules due to absence of cellulase enzyme. (ii) (b): Finger-like projections that come out from mucosa of intestine form villi. Cells lining the villi produce numerous microscopic projections called microvilli giving a brush border appearance which increase the surface area for absorption enormously. Villi has a good supply of capillaries and a large lymph vessel for absorption of nutrients. If the inner lining of the small intestine will be smooth, the surface for absorption will be reduced. (iii) (a) (iv) (c) (v) (b)

(i) (a): Urea solution is more concentrated than the sap present in plant cells, so plant cells lose water to the soil through the process of exosmosis. Loss of water caused plant to die. (ii) (b) (iii) (d): Diffusion keeps the cell walls of the internal plant tissues moist. It is a means of spreading of ions and other substances through protoplast. Transpiration or loss of water in vapour form is a diffusion process. Exchange of gases during photosynthesis and respiration between the plant interior and outside air also occurs through diffusion. (iv) (b) (v) (b)

(i) (b): In the given figures B represents artery that carry blood away from the heart to different organs. (ii) (c): In the given figures, A represents vein. Veins bring blood from different body parts to the heart. The flow of blood in veins is not so fast because the blood in veins is under low pressure. Veins possess valves which prevent backward flow of blood. (iii) (a): Veins carry deoxygenated blood with single exception, i.e., pulmonary vein. Arteries carry blood from heart towards the organ. (iv) (d) (v) (a)

(i) (b): Nitrogenous waste substances such as ammonia, urea or uric acid are produced during protein metabolism. Ammonia is the most toxic, followed by urea and uric acid. Uric acid is least toxic. (ii) (c) (iii) (b): Urea is a nitrogenous waste formed as a result of metabolism of various food/beverages in the body and is excreted in the urine. So,if a person is not taking food/beverages he will have less urea in his urine. (iv) (c) (v) (a): Malpighian corpuscle (A) is the site of ultrafiltration. A considerable amount of water is reabsorbed in the collecting duct (E) under the influence of ADH. Proximal convoluted tubule (C) is the main site for the reabsorption of glucose and amino acids. In distal convoluted tubule (D), bothhydrogen ions and ammonium ions are secreted, thus it maintains blood pH.

(i) (c): Basophiles release heparin, serotonin and histamine. They are like mast cells of connective tissue and are not phagocytic in nature. (ii) (c) (iii) (c) : WBCs manufacture antibodies, which fight against disease causing germs and are responsible for immunity, thus called soldiers of the body. (iv) (d) (v) (a): Lymph is a colourless fluid, which contains blood plasma along with leucocytes and have fewer proteins.

(i) (c): In the test tube full of mercury (figure A) there is no air and, therefore, the introduced soaked seeds do not get air for aerobic respiration. But they are capable of respiration in the absence of oxygen as is indicated by the evolution of carbon dioxide (figure B). Therefore, anaerobic respiration takes place in the seeds in the absence of free oxygen. The experiment also shows that CO 2 is evolved in anaerobic respiration of seeds. (ii) (b) (iii) (d): The given process is an example of alcoholic fermentation, thus the gas produced is CO 2 . (iv) (c): Ethyl alcohol fermentation occurs in fungi such as Rhizopus, yeast and bacteria. (v) (a): Muscle fatigue is the reduction in force of contraction of a muscle after prolonged stimulation. In the absence of oxygen, skeletal muscle of human beings can contract for a short time, but it gets fatigued soon. This is due to the fact that in the absence of oxygen, products of glycolysis mainly lactic acid is not disposed off and accumulates in the muscles. This leads to muscle fatigue and pain in the muscles. A muscle gets fatigued sooner after a strenuous exercise than after a mild exercise. Faster breathing for sometime after a strenuous exercise supplies extra oxygen, disposes off excess lactic acid and muscle fatigue disappears.

(i) (c): A- Artery: Carries blood from heart to different body parts. It is thick-walled and elastic. It acts as a "pressure reservoir" for maintaining the blood flow. B - Capillary : Nutrients, hormones, gases, etc. can diffuse into tissue cells through capillaries and vice versa. It is thin-walled, and only one cell layer thick resting on basement membrane. C - Vein: Brings blood from different body parts to the heart. It is thin-walled and act as low-resistance conduct for blood flow. D - Pulmonary vein: Two pulmonary veins from each lung transport the oxygenated blood to the left atrium. (ii) (d): In amphibians, the left atrium receives oxygenated blood from the gills/lungs/skin and the right atrium gets the deoxygenated blood from other body parts. However, they get mixed up in the single ventricle which pumps out mixed blood i.e., incomplete double circulation (iii) (d): Whale is a mammal and in mammals, two separate circulatory pathways are found - systemic circulation and pulmonary circulation. Oxygenated and deoxygenated bloods received by the left and right atria respectively pass on to the left and right ventricles. Thus, oxygenated and deoxygenated bloods are not mixed. This is referred to as double circulation. (iv) (a) (v) (c): Pulmonary circulation is the movement of blood between heart and lungs. During this pathway deoxygenated blood entering the right atrium, moves into the right ventricle. From here it moves through the pulmonary arch into the lungs for oxygenation. Then from lungs the oxygenated blood moves into the left atrium through pulmonary veins.

(i) (d) (ii) (d) (iii) (b): The epidermal surface of the leaf exhibits a large number of minute openings called stomata. The stomata are bordered by two specialized epidermal cells - the guard cells which in some cases are accompanied by subsidiary cells. The walls of guard cells are unevenly thickened. Each guard cell has thick, inelastic inner wall and thin, elastic outer wall. Stomatal aperture is present in between the guard cells. Guard cells are not always surrounded by accessory cells or subsidiary cells. (iv) (b) (v) (a)

(i) (c) : Number of RBCs per cubic millimetre of blood is likely to be higher in people living at high altitudes. This is in response to the air being less dense at high altitude and thus more RBCs (and hence more Hb) are needed to absorb the required amount of O 2 from the air having low pO 2 (partial pressure of O 2 ). (ii) (c): The change from II to III indicates decrease in the volume of lungs and thus, increase in the pressure of air inside the lungs. This results in movement of air out of the lungs. (iii) (c) (iv) (b): p-pharynx, q-trachea, r-alveoli, s-diaphragm, t-ribs (v) (c)

(i) (d): In light reaction of photosynthesis assimilatory power is produced, i.e., energy rich ATP molecules and reduced coenzyme NADPH. (ii) (d): The equation of photosynthesis may be represented as \(6 \mathrm{CO}_{2}+12 \mathrm{H}_{2} \mathrm{O} \rightarrow \mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{6}+6 \mathrm{H}_{2} \mathrm{O}+6 \mathrm{O}_{2}\) No. of C 6 H 12 O 6 (sugar) molecules produced =1 (iii) (c) (iv) (b): Light reactions (or photochemical phase) of photosynthesis mainly occur on the grana thylakoids. Dark reactions (or biosynthetic phase) which involve synthesis of carbohydrates by CO 2 fixation, occur inthe stroma (or matrix) of chloroplasts. The chloroplast matrix of higher plants stores starch temporarily in the form of starch granules. (v) (b): Light reactions are also called photochemical phase whereas dark reactions are also called biochemical phase.

(i) (c): Goblet cells or mucous cells are present throughout the epithelium of gastric glands and secrete mucus, which protects gastro-intestinallining from enzymatic action. (ii) (a) (iii) (c) (iv) (b): Pepsin and trypsin both are protein digesting enzymes, but they work at different locations and different pH in alimentary canal. Pepsin, which is most active at pH of 1.5 to 2.5, is an important peptic enzyme in stomach. Trypsin, which is a pancreatic protease, acts mostly in upper small intestine (duodenum and jejunum), works at an optimum pH of 7.5 - 8.5. (v) (c): The absorptive surface of small intestinal mucosa have many folds, which increase its surface area. Also located on epithelial surface of small intestine are millions of small villi. Intestinal epithelial cell on each villus is characterised by a brush- border which further increases the surface area. Thus, to compensate for this and to have effective absorption of nutrients, intestine would need to be much longer in length.

(i) Krebs' cycle takes place in mitochondrial matrix. (ii) (b) (iii) (a) : Glycolysis does not utilise any oxygen as it is an anaerobic process. (iv) (d) (v) (d): In aerobic respiration, glucose is completely broken down to CO 2 and H 2 O with the production of a large amount of energy (ATP).

(i) (b): Yeast, mushroom and bread mould have a saprophytic mode of nutrition which is chemoheterotrophic in nature. They breakdown complex organic substances by secreting digestive enzyme outside their body and absorb simple molecules as nutrients. (ii) (b) (iii) (b): Yeast, mushroom and bread mould have a saprophytic mode of nutrition which is chemoheterotrophic in nature. They breakdown complex organic substances by secreting digestive enzyme outside their body and absorb simple molecules as nutrients. (iv) (c): Heterotrophic nutrition is mode of nutrition in which an organism depends on other living organisms for food. (v) (a)

(i) (d) (ii) (c): Baked potatoes consist of starch which is a polysaccharide. In oral cavity, the food is mixed with saliva that contains an enzyme salivary amylase which converts starch into maltose, isomaltose and small dextrins. The pancreatic juice (present in small intestine) contains pancreatic amylase which converts starch into maltose, isomaltose and \(\alpha\) -dextrins. \(\text { Starch } \frac{\text { Pancreatic }}{\alpha \text { -amylase }}>\text { Maltose }+\text { Isomaltose }+\alpha \text { -Dextrins }\) Further, disaccharidases such as maltase (present in intestinal juice in small intestine) break down disaccharides such as maltose into monosaccharides or simpler sugars. (iii) (d): After removal of gall bladder, bile could no longer to be stored and hence fat metabolism would be affected. Therefore, fat intake should be restricted. (iv) (d) (v) (c)

(i) (b) (ii) (a): Food is transported by vascular tissue phloem from source to sink. Source is a part that synthesise food and sink is a part that stores or needs the food. Since source and sink can be reversed depending on plant's need, therefore direction of movement of sugar in phloem can be bidirectional, i.e., both upwards or downwards. (iii) (b) (iv) (c)

Life Processes Extra Questions Short Answer Type

Question 1. What is compensation point? Answer: When the rate of photosynthesis is equal to rate of respiration, it is called as compensation point. The rate of liberation of O 2 during photosynthesis is equal to the rate of liberation of CO 2 during respiration. Thus, there is no net uptake of gases from the environment. Compensation point is usually reached at dusk and dawn and on a cloudly day.

Question 2. What happens to visible light of the sun when it falls on chlorophyll? Answer: Visible light of the sun consists of seven colours-violet, indigo, blue, green, yellow, orange and red. Out of these lights of different wavelengths, chlorophyll absorbs mainly blue, violet, red and orange lights but does not absorb the green light. It is due to the reflection of green light by chlorophyll of the plants that the plants look green in colour.

Question 3. “All plants give out oxygen during day and carbon dioxide during night”. Do you agree with this statement? Give reason. Answer: During day time, as the rate of photosynthesis is more than the rate of respiration, the net result is evolution of oxygen. At night there is no photosynthesis, so they give out carbon dioxide due to respiration.

Question 4. How does water affect the rate of photosynthesis in plants? Answer: Water controls the opening and closing of stomata. The deficiency of water causes stomata to open very little or it may even remain closed. Therefore, it (required as a raw material for photosynthesis) cannot enter into the leaves and thus lack of water slows down the rate of photosynthesis.

Question 5. What is peptic ulcer? How is peptic ulcer caused? Answer: An ulcer on the inner membrane lining of the stomach is called peptic ulcer. Peptic ulcer is caused by the high acidity of gastric juice secretions.

Question 6. How does respiration occur in the leaves? Answer: Leaves have tiny opening on their lower surface called stomata. The exchange of gases takes place through the stomata by the process of diffusion.

Question 7. What is ascent of sap? Answer: Absorbed water from the soil also contains dissolved minerals (nitrates, phosphates, etc.) and hence it is called sap. This sap moves upwards due to the ‘transpiration pull’ developed in the xylem elements. Thus, transportation of sap from roots to the leaves at the top is called ascent of sap.

Question 8. What is transpiration pull? Answer: Water in the mesophyll cells of leaves (cells located below the stomata) is in contact with water or sap in xylem of leaf petiole, stem and root. This water evaporates by the process of transpiration. Thus, due to transpiration water is pulled upward which creates an upward suction force called ‘transpiration pull’.

Question 9. Plants have low energy needs as compared to animals. Explain. Answer: Plants do not move. In a large plant body there are many dead cells like schlerenchyma which provide strength to the plant but do not perform any cellular function. As a result they requires less energy. Animals, on the other hand, need energy for different activities like movement or search of food. SO 2 they require more energy.

Question 10. What is root pressure? Answer: It is a pressure developed in the xylem due to metabolic activity of the root cells. It is a hydrostatic pressure developed in the root system that pumps the water or sap in the root xylem.

Question 11. How do leaves of plants help in excretion? Answer: Many plants store waste materials in the vacuoles of mesophyll cells and epidermal cells. When old leaves fall, the waste materials are excreted along with the leaves.

Question 12. What is the role of intercostal muscles in respiration and where are these found? Answer: Intercostal muscles are found in between the ribs. Their contraction and relaxation changes the volume of thoracic cavity so that air can enter and leave the lungs.

Question 13. State the function of Bowman’s capsule and glomerulus. Answer: Bowman’s capsule and glomerulus have semipermeable walls. The glomerulus, is a tuft of capillaries contained in Bowman’s capsule. The water and dissolved substances (wastes and useful) are filtered into the Bowman’s capsule and from here they are filtered into the tubule. Thus, both the structures act as filtering apparatus.

Question 14. What causes movement of food inside the alimentary canal? Answer: The wall of alimentary canal contains muscle layers. Rhythmic contraction and relaxation of these muscles pushes the food forward. This is called peristalsis, which occurs all along the gut.

Question 15. What happens to glucose which enters the nephron along with the filtrate? Answer: Glucose along with filtrate runs down through the long renal tubule by the action of cilia. Glucose, amino acids, salts, etc., are reabsorbed by the tubular cells and then secreted into the capillary blood cells by diffusion.

Question 16. Name the correct substrates for the following enzymes:

Question 17. Write down the functions of lymph nodes. Answer: Functions of lymph nodes are:

Lymph nodes produce and maintain the lymphocytes of blood. These are only found in the mammals.
Lymph nodes filter the blood and remove poisonous and foreign substances, e.g., bacteria, debris, etc.

Life Processes Class 10 Extra Questions with Answers Science Chapter 6 1

Question 19. State the function of epiglottis. Answer: At the top of the trachea (or wind pipe) there is a flap of cartilage called epiglottis. The function of epiglottis is to cover the mouth of trachea (or wind pipe) when we swallow food so that the food may not enter the trachea (or wind pipe).

Question 20. Why are white blood corpuscles called soldiers of the body? Answer: White blood corpuscles engulf (phagocytose) the foreign matter (bacteria, dust and other foreign material) entering the body, and are hence called soldiers. They produce antibodies against antigens, and antitoxins against toxins.

Question 21. Describe the importance of stomata in plant. Answer: Plants release gaseous wastes such as CO 2 produced during respiration at night and O 2 produced during photosynthesis in daytime through stomata on leaves and lenticels found on stems.

Question 22. What happens to the rate of breathing during vigorous exercise and why? Answer: During vigorous exercise, our body requires more energy and for this purpose more oxygen is needed, so the rate of breathing is increased. Oxygen intake rate increases by about 20 to 25 times.

Question 23. How do the guard cells regulate opening and closing of stomatal pores? Answer: The swelling of guard cells due to absorption of water causes opening of stomatal pores while shrinking of guard cells closes the pores. Opening and closing of stomata occurs due to turgor changes in guard cells. When guard cells are turgid, stomatal pore is open while in flaccid conditions, the stomatal aperture closes.

Question 24. Two green plants are kept separately in oxygen-free containers, one in the dark and the other in continuous light. Which one will live longer? Give reasons. Answer: Plant kept in continuous light will live longer. Because it will be able to produce oxygen required for its respiration by the process of photosynthesis.

Question 25. In each of the following situations what happens to the rate of photo synthesis?

Cloudy days
No rainfall in the area
Good manuring in the area
Stomata get blocked due to dust.

Question 26. Name the energy currency in the living organisms. When and where is it produced? Answer: Adenosine triphosphate (ATP) is the energy currency in the living organisms. It is produced in the mitochondria during respiration in living organisms and also during photosynthesis in plants.

Question 27. Explain the role of mouth in digestion of food. Answer:

Food is crushed into small pieces by the teeth.
It mixes with saliva and the enzyme amylase (found in saliva) breaks down starch into sugars.
Tongue helps in thorough mixing of food with saliva.

Question 28. Explain the statement, ‘Bile does not contain any enzyme but it is essential for digestion.’ Answer: Bile does not contain any enyzme but it is essential for digestion because bile is alkaline and contain salts which helps to emulsify the fat present in the food. SO 2 the bile perform two functions:

The food coming from the stomach is acidic and has to be made alkaline for the pancreatic enzymes to act.
The bile salts breakdown the fat present in the food into smaller globules. This increases the efficiency of enzymes in the small intestine to digest the food effectively.

Question 29. Why is blood circulation in human heart called double circulation? Answer: The blood circualtion in human heart is called double circulation because the blood passes through the heart twice in one complete cycle of the body i.e., once through the right half in the form of deoxygenated blood and once through the left half in the form of oxygenated blood.

Question 30. What are the adaptations of leaf for photosynthesis? Answer:

Leaves provide large surface area for maximum light absorption.
Leaves are arranged at right angles to the light source in a way that causes overlapping.
The extensive network of veins enables quick transport of substances to and from the mesophyll cells.
Presence of numerous stomata for gaseous exchange.
The chloroplasts are more in number on the upper surface of leaves.

Life Processes Class 10 Extra Questions with Answers Science Chapter 6 2

Question 32. Why does absorption of digested food occur mainly in the small intestine? Answer: Maximum absorption occurs in small intestine because:

digestion is completed in small intestine.
inner lining of small intestine is provided with villi which increases the surface area for absorption.
wall of intestine is richly supplied with blood vessels which take the absorbed food to each and every cell of the body.

Question 33. What substances are contained in the gastric juice? What are their functions? Answer: Gastric juice contains three substances: hydrochloric acid, enzyme pepsin and mucus. Their functions are:

Hydrochloric acid in the stomach is used to make the medium acidic to facilitate the action of the enzyme pepsin and to kill germs if any.
Enzyme pepsin digests proteins to convert them into peptones.
The mucus helps to protect the stomach wall from its own secretions of hydrochloric acid.

Question 34. What are the various processes that take place in the duodenum? Answer: Processes that take place in the duodenum are:

Bile emulsifies the fat molecules present in the food into small globules.
The pancreatic enzyme trypsin starts digesting the proteins and the pancreatic amylase breaks down the starch.
Bile juice secreted by the liver and bicarbonate ions secreted by the duodenal wall makes the medium alkaline.

Question 35. How does respiration occur in the roots of the plant? Answer: Air is present in between the particles of the soil. The roots take the oxygen by the. process of diffusion. Oxygen first diffuses into the root hairs and reaches all other cells of the root for respiration. CO 2 produced in the cells moves out through the root hairs, by the process of diffusion. For respiration, in older roots, where root hair is not present, the exchange of gases takes place through lenticels (tiny openings in the protective layer) by the process of diffusion.

Question 36. (i) Explain why the rate of photosynthesis in plants is low both at lower and higher temperatures. (ii) Is green light most or least useful in photosynthesis and why? Answer: (i) Photosynthesis is an enzymatic process. The enzymes function within an optimum range of temperature which is neither very low nor very high. At low temperature the activity of enzymes is lowered due to which the rate of photosynthesis is also low. Again when the temperature is very high, the activity of enzymes decreases which leads to low rate of photosynthesis.

(ii) Green light is least useful in photosynthesis, because chlorophyll does not absorb green light.

Question 37. Though what conduction of water in plants takes place? Explain its mechanism. Answer: Transport of water in plants: The transport or movement of soluble products (sugar) of photosynthesis from leaves to other parts of the plant is known as translocation. It occurs is the part of vascular tissue known as pheloem. Besides the product of photosynthesis, phloem also transports amino acids and other substances (such as plant harmones). These substances are especially delivered to storage organs of roots, fruits, seeds and growing organs.

Question 39. State the functions of the following components of transport system: (i) Blood (ii) Lymph. Answer: (i) The following are the important functions of blood: (a) It transports the digestive component of food to all the body cells. (b) It also transports respiratory gases to body cells. (c) It carries waste product for excretion. (d) It acts as carrier of hormones. (ii) Lymph contains lymphocyte cells which fight against infection and it also carries digested fat.

Question 40. What is the advantage of having four chambered heart? Answer: In four chambered heart, left half is completely separated from right half by septa. This prevents oxygenated and deoxygenated blood from mixing. This allows a highly efficient supply of oxygenated blood to all parts of the body. This is useful in animals that have high energy needs, such as birds and mammals.

Life Processes Class 10 Extra Questions with Answers Science Chapter 6 4

Question 42. What is autotrophic nutrition? Explain in brief with example. Answer: Autotrophic Nutrition: Some organisms use simple food materials obtained from inorganic sources in the form of carbon dioxide and water. These organisms are called autotrophs. Ex. Green plants and some bacteria. This mode of nutrition is called autotrophic nutrition.

Life Processes Class 10 Extra Questions with Answers Science Chapter 6 5

Question 45. What is transpiration? Write down four factors affecting transpiration process. Answer: Transpiration: Water loss from the aerial parts of the plant is called transpiration. Following factors are there to influence the process of transpiration. (i) Humidity: There is an increase in transpiration when atmospheric humidity decreases, while transpiration decreases with increase in humidity. (ii) Speed of Air: High speed of air causes higher rate of transpiration. But when the air speed is high, stomata get closed and causes a decrease in transpiration. (iii) Temperature: Increased atmospheric temperature causes decrease in humidity of air. This causes increase in transpiration. When temperature decreases, decrease in transpiration takes place. (iv) Light Intensity: When intensity of light increases it causes increase in temperature and decrease in atmospheric humidity which causes increased rate of transpiration.

Question 2. What are the common features between all the respiratory organs? Explain the mechanism of gaseous exchange between tissues and blood. Answer: Common features between all the respiratory organs are:

All the respiratory organs have large surface areas to get enough oxygen.
All the respiratory organs are thin-walled for easy diffusion of gases and substances.
All the respiratory organs (like skin, lungs, gills) have a rich supply of blood for transporting respiratory gases.

The mechanism of gaseous exchange between tissues and blood is as follows:

The blood reaching the tissues has higher concentration of oxygen than in the cells so it gets diffused into the cells.
the carbon dioxide, which is formed in the cells, gets accumulated in higher concentration as compared in the blood, so it easily diffuses into the blood.
The blood with CO 2 takes this gas to the lungs, from where it is expelled out during exhalation.

Life Processes Class 10 Extra Questions with Answers Science Chapter 6 9

Question 4. Give the role of liver in the human beings. Answer: Liver is the largest gland in human beings. Its main functions are as follows:

It secretes bile juice which makes the medium of the food alkaline Amoeba and also emulsifies fat.
It stores the excess of glucose in the form of glycogen.
Old worn-out RBC’s are broken down in liver cells. Their haemoglobin is changed into bile pigments.
The ammonia is produced as a result of metabolism of amino acids. It is highly toxic. The ammonia combines with CO 2 and is converted into urea (less toxic).
It stores vitamins, iron and copper.
It produces fibrinogen and helps in blood-clotting.
It produces heparin which does not allow the clotting of blood inside the blood vessels.
It regulates the volume of blood to some extent.
RBCs are produced at the foetal stage by the liver.

Question 5. (i) Describe aerobic respiration. (ii) Describe the process of anaerobic respiration. Or What is A.T.P.? How is it formed? What is the use of it? Answer: (i) The respiration which needs oxygen or occurs in the presence of oxygen is called aerobic respiration. During this type of respiration, glucose is broken down into carbon dioxide and water with the release of considerable amount of energy. The energy is stored in the form of ATP.

Life Processes Class 10 Extra Questions with Answers Science Chapter 6 10

Mechanism of breathing: (i) When we breathe in air, the diaphragm contracts which results in the increase in volume of chest cavity. Due to this expansion of chest cavity, the air pressure in the lungs decreases. Thus, air from outside rushes into the lungs through nostrils, trachea and bronchi. Therefore, air sacs of lungs get filled with air when we breathe in. The exchange of gases between alveoli and blood takes place by the process of diffusion.

(ii) Human respiratory system: Now, the air present in air sacs of the lungs in rich in CO 2 . When we breathe out air, the diaphragm relaxes which results in the decrease in volume of chest cavity. This contraction pushes the air from the lungs into the trachea, nostrils and then out of the body into air. Breathing in air is called inhalation and breathing out air is called exhalation.

Mechanism of gaseous exchange during respiration: The oxygen is carried by blood to all the parts of the body. As the blood passes through the tissues of the body, the oxygen from the blood diffuses into the cell, whereas the CO 2 which is produced during respiration diffuses into the blood and is carried to the lungs.

Life Processes Class 10 Extra Questions with Answers Science Chapter 6 15

(ii) Digestion: The teeth helps in physical digestion of food. In mouth there are salivary glands, which secretes saliva, in which salivary amylase enzyme is present which digest the starch present in food into maltose sugar, i.e., the digestion of carbohydrate starts from mouth itself. Mouth opens into a small funnel-shaped area called pharynx which leads to a long tube called oesophagus, whose wall is highly muscular.

When the slightly digested food enters into oesophagus the contraction and expansion movement of its wall, takes place, which is known as peristaltic movement. This movement helps the food to move towards the stomach. Usually, in oesophagus there is no digestion of food. From the oesophagus the food enters into the stomach.

In the stomach there is secretion of gastric juices which is a mixture of hydrochloric acid, pepsin (protein Colon digesting enzyme) and mucus. Now, the partially digested food enters from stomach into the small intestine’s wider part which is known as duodenum and the remaining part of the small intestine is termed as ileum.

The duodenum, receives secretions of two glands, i.e., liver and pancreas. Liver secretes bile pigments and pancreas secretes pancreatic juice which digestes the proteins, carbohydrates and emulsified fats. Here the digestive enzymes are amylase, maltose and invertase for digesting the carbohydrates, trypsin for proteins and lipase for fats.

Thus, food is completely digested in ileum part of small intestine. (iii) Absorption: Now, the food enters from duodenum into ileum part of small intesntine where millions of finger-like projections known as villi are present which absorb the food.

(iv) Assimilation: The blood carries the digested and dissolved food to all parts of the body, where it is assimilated into the cells which is used for obtaining energy as well as for growth and repair of the body.

(v) Egestion: The undigested food enters into the large intestine’s wider part, where water is absorbed from the undigested food and the food becomes solid. Now, this solid undigested food enters the last part of large intestine known as rectum through which it moves out from the body.

Life Processes Class 10 Extra Questions with Answers Science Chapter 6 17

The two auricles (atria) are separated from the ventricles by two apertures guarded by membranous valves. The valve separating right atrium from right ventricle is called right atrio-ventricular valve or tricuspid valve made up of three flaps. The valve separating left atrium from left ventricle is called left atrio-ventricular valve or mitral valve, formed of two flaps. These valves are attached with fine cords with the papillary muscles of the ventricular wall.

These valves only allow blood flow from auricles into ventricles and not in opposite direction. Both the ventricles are separated from each other by a thick inter-ventricular septum. The wall of left ventricle is much thicker than that of right ventricle. The left ventricle pushes blood into aorta which supplies blood to entire body. The opening of aorta is also guarded by a valve formed of 3 semilunar flaps.

The right ventricle pumps venous blood into lungs by a pulmonary aorta. Its opening is also guarded by a valve, having 3 semilunar flaps. These valves allow the flow of blood from ventricles into the aorta and not back. Heart is formed of cardiac muscle fibres, which rhythmically contract the heart without feeling fatigue.

Question 13. Write a brief account on composition and functions of human blood. Answer: It is slightly thicker than water and is slightly basic with a pH 7.3-7.4. Two main components of blood are: (i) Plasma: It forms about 55% of the blood which have 90% water and 10% complex organic and inorganic compounds. It is called inanimate part of blood because it lacks blood corpuscles. Organic compounds in plasma include antibodies, glucose, amino acids, hormones, enzymes, fatty acids, vitamins and proteins (i.e., albumin, globulin, prothrombin, fibrinogen, heparin).

Heparin acts as anticoagulant in blood. It prevents clotting of blood in blood vessels. On the contrary, prothrombin and fibrinogen help in formation of clot during an injury. Inorganic compounds include potassium, sodium, calcium, magnesium and their compounds in the wound form of phosphate, biocarbonate, sulphate, chloride, etc.

(ii) Blood Corpusscles: They form about 45% of the blood composition. (See Fast Track Revision): Function of Blood Transport of Gases: Blood transports gases like bind O 2 and CO 2 . RBCs present in blood have haemoglobin which bind with O 2 and form oxyhaemoglobin. This oxyhaemoglobin breaks down into O 2 and haemoglobin in tissues. O 2 is absorbed by tissues, while haemoglobin and bicarbonates help in CO 2 transport. Transport of Nutritive Materials: Nutritive materials absorbed by intestine transported to tissues by plasma.

Transport of Excretory Materials: In body, by metabolic process many excretory products such as urea, etc., are formed. This is transported to liver and then to kidney. Regulation of Body Temperature: Blood maintains temperature of all body parts and also helps in transport of hormones.
