Answer:
Correct Answers
- To convert light energy into chemical energy (glucose).
- D. Soil
- 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
- B. Chlorophyll a
- In the chloroplasts, primarily in the mesophyll cells of leaves.
- E. It drives the water-splitting reaction.
- Oxygen (O₂)
- B. To synthesize glucose.
- During the daytime (when sunlight is available).
- Light-dependent reactions and Calvin cycle.
