The Correct Option is B

Solution and Explanation

Chlorophyll has magnesium in its centre. The chlorophylls are basically chelate salts of magnesium (Mg). The chlorophyll-a has a molecular formula $C_{55}H_{72}O_5N_4Mg$. Chlorophyll molecule is distinguishable into head of size $15 \times 15$? and a tail o f $20 ? $ length.

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:

  1. Calvin Cycle (C3 Cycle)
  2. C4 Cycle (Hatch and Slack Pathway)
