ARYA PUBLIC SCHOOL , CHANDLANA
CLASS -10TH ( ASSIGNMENT- LIFE PROCESSES )
1. Most of the digestion and absorption of the food takes place in the
(a) small intestine
(b) liver
(c) stomach
(d) large intestine.
2. Mention the raw materials required for photosynthesis.
3. State the location and function of gastric glands.
4. Name the glands present in the wall of the stomach that release secretions for digestion of
food. Write the three components of secretion that are released by these glands.
5. Complete the following flow chart as per the given instructions.
6. (a) State the role played by the following in the process of digestion :
(i) Enzyme trypsin
(ii) Enzyme lipase-
(b) List two functions of finger-like projections present in the small intestine.
7. Explain the significance of photosynthesis. Write the balanced chemical equation involved in
the process.
8. Differentiate between autotrophs and hetero- trophs and give one example of each.
9. Explain with the help of neat and well labelled diagrams the different steps involved in nutrition
in Amoeba.
10. (a) What is peristaltic movement?
(b) ‘Stomata remain closed in desert plants during daytime’. How do they do photosynthesis?
11. Why is nutrition necessary for the human body?
(b) What causes movement of food inside the alimentary canal?
(c) Why is small intestine in herbivores longer than in carnivores?
(d) What will happen if mucus is not secreted by the gastric glands?
12. (a)State the form in which the following are stored:
(i) Unused carbohydrates in plants.
(ii) The energy derived from food in humans,
(b) Describe the process of nutrition in Amoeba with the help of diagram.
13. Anaerobic process
(a) takes place in yeast during fermentation
(b) takes place in the presence of oxygen
(c) produces only energy in the muscles of human beings
(d) produces ethanol, oxygen and energy.
14. Diffusion is insufficient to meet the oxygen requirement of multicellular organisms like human.
State reason.
