- Organic chemicals
- Light
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
The green cells of the plant convert the solar energy into chemical energy by the process known as photosynthesis. The importance of photosynthesis lies in the transformation of low energy compounds ( $ C{{O}_{2}} $ and $ {{H}_{2}}O $ ) into high energy compounds (carbohydrates).

Photosynthesis in Higher Plants
Processes Of Photosynthesis in Higher Plants:
Photosynthesis in higher plants involves the following processes:
- Light Reaction
- Dark Reaction
Light Reaction:
- This phenomenon occurs in the presence of light.
- The pigment absorbs light and produces energy in the form of ATP.
- The process involves- absorption of light, water splitting, the release of oxygen, and formation of ATP and NADPH.
Dark Reaction:
This process occurs in the absence of light in the stroma of the chloroplasts. The following cycles are involved in the process:
- Calvin Cycle (C3 Cycle)
- C4 Cycle (Hatch and Slack Pathway)
