Q6.
Assertion (A): Photosynthesis occurs only during the daytime.
Reason (R): Sunlight is required for the process of photosynthesis.
Q7.
Assertion (A): Stomata regulate the exchange of gases in plants.
Reason (R): Stomata are surrounded by guard cells.
Q8.

Reason (R): Villi help in the movement of food in the intestine.
Q9.
Assertion (A): Fungi obtain their food by saprophytic mode of nutrition.
Reason (R): Fungi secrete digestive enzymes on dead organic matter.
✍️ SECTION C: Short Answer Questions (2 × 5 = 10 Marks)
Q10. Name two raw materials required for photosynthesis. How are they obtained by plants? (2 marks)
Q11. How do guard cells regulate the opening and closing of stomatal pores? (2 marks)
Q12. What is the function of hydrochloric acid in the stomach? (2 marks)
Q13. Define the following:
- (a) Saprophytic nutrition
- (b) Parasitic nutrition (2 marks)
Q14. Write any two differences between autotrophic and heterotrophic nutrition. (2 marks)
✏️ SECTION D: Short Answer Type-II (3 × 3 = 9 Marks)
Q15. Explain the mechanism of photosynthesis (3 marks)
Q16. Define nutrition. Why is it essential for organisms? Name two modes of nutrition. (3 marks)
Q17. Explain the process of digestion in Amoeba with a labeled diagram. (3 marks)
📚 SECTION E: Case-Based Question (4 × 1 = 4 Marks)
Q18. Read the passage and answer the following questions:
Salivary glands in the mouth secrete saliva which contains an enzyme. This enzyme breaks down starch into sugars. The stomach secretes hydrochloric acid which creates an acidic medium. Pepsin acts in this acidic environment to digest proteins. The digested food moves to the small intestine, where it is absorbed by the villi.
(a) Name the enzyme present in saliva.
(b) What is the function of HCl in the stomach?
(c) Which organ is responsible for absorption of food?
(d) Why are villi important in the small intestine?
📖 SECTION F: Long Answer Questions (5 × 2 = 10 Marks)
Q20. Describe the human digestive system. Draw a labeled diagram and explain the functions of liver and pancreas. (5 marks)
