Biology Practice: Photosynthesis & Respiration (Mock Test 3 - Advanced)
1. Why is photosynthesis considered a "Building" or Anabolic process?
2. During the Light reaction, what is the fate of the Oxygen produced from water splitting?
3. What is the main reason plants perform 'Dark Reactions' in the stroma?
4. Why does a plant kept in a dark room for 48 hours fail the Iodine test for starch?
5. Functional difference: How does the energy release in Respiration differ from Combustion (burning)?
6. What happens to the rate of photosynthesis if the light intensity is increased beyond a certain limit?
7. Why is ATP called the "Energy Currency" of the cell?
8. In the "Moll's Half-Leaf" experiment, why does the part of the leaf inside the bottle NOT turn blue-black with Iodine?
9. What is the primary difference between Aerobic and Anaerobic respiration in terms of end products?
10. Why do roots need air spaces in the soil for respiration?
11. During the day, the net gas exchange in a leaf is:
12. Why do we boil the leaf in water before alcohol during the starch test?
13. Which wavelength of light is least absorbed by chlorophyll?
14. What is the significance of the "Compensation Point"?
15. How does $CO_2$ enter the mesophyll cells of a leaf?
16. Why is anaerobic respiration less efficient than aerobic respiration?
17. In the experiment with Hydrilla, what proves the gas collected is Oxygen?
18. Respiration that occurs in our muscles during a 100m sprint results in:
19. The folds of the inner mitochondrial membrane where respiration enzymes are located are:
20. What would happen to the earth's atmosphere if photosynthesis stopped completely?
