Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Magnesium is a constituent of chlorophyll. Chlorophylls are the green photosynthetic pigments. Five types of chlorophylls $a, b, c, d$ and $e$ occur in plants. Out of these only chlorophylls a and b occur in the chloroplasts of higher plants. Molecular formula of chlorophyll $a, b, c$ and $d$ are $C_{55}H_{72}O_{5}N_{4}\,Mg, C_{55}H_{70}O_{6}N_{4}\,Mg, C_{35}H_{32}O_{5}N_{4}\,Mg$ and $C_{54}H_{70}O_{6}N_{4}\,Mg$ respectively. Chlorophyll $e$ is a rare type found in some golden algae.

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)
