1. The process by which green plants make their food is called:
Answer: B. Photosynthesis
Photosynthesis is the process where green plants prepare food using carbon dioxide, water, sunlight, and chlorophyll, producing glucose and oxygen.
2. The green pigment in leaves is:
Answer: B. Chlorophyll
Chlorophyll absorbs sunlight energy required for photosynthesis. It gives leaves their green color.
3. Which gas is taken in during photosynthesis?
Answer: C. Carbon dioxide
Plants absorb carbon dioxide from air through stomata for preparing food.
4. The food prepared by plants is stored as:
Answer: C. Starch
Glucose formed during photosynthesis is converted into starch for storage.
5. Organisms that make their own food are called:
Answer: B. Autotrophs
Autotrophs like green plants prepare their own food using sunlight.
6. Cuscuta is an example of:
Answer: B. Parasite
Cuscuta derives nutrition from host plants and cannot make its own food.
7. Pitcher plant traps insects to obtain:
Answer: B. Nitrogen
Insectivorous plants grow in nitrogen-deficient soil, so they trap insects.
8. Fungi obtain nutrition by:
Answer: B. Saprotrophic nutrition
Fungi feed on dead and decaying organic matter.
9. Stomata are present in:
Answer: C. Leaves
Stomata are tiny pores that allow gas exchange.
10. Water is transported in plants through:
Answer: B. Xylem
Xylem carries water and minerals from roots to leaves.
11. Sunlight provides energy for:
Answer: B. Photosynthesis
Solar energy drives the food-making process.
12. Lichens show which nutrition?
Answer: A. Symbiotic
Algae and fungi live together benefiting each other.
13. Plants synthesise food mainly in:
Answer: C. Leaves
Leaves contain chlorophyll and are main photosynthetic organs.
14. Oxygen released during photosynthesis comes from:
Answer: B. Water
Water molecules split to release oxygen.
15. Heterotrophs depend on:
Answer: B. Other organisms
They cannot make their own food.
16. The test for starch uses:
Answer: B. Iodine
Iodine turns blue-black in presence of starch.
17. Desert plants have fewer stomata to:
Answer: B. Reduce water loss
Fewer stomata help conserve water.
18. Nutrition mode of mushrooms:
Answer: B. Saprotrophic
They feed on decaying matter.
19. The raw materials for photosynthesis are:
Answer: B. CO₂ & water
These combine in presence of sunlight to form food.
20. Which part absorbs water?
Answer: B. Root hairs
Root hairs increase surface area for absorption.
