The Correct Option is B

Solution and Explanation

Grana are present inside the chloroplasts. Each granum may contain 10 - 100 thylakoids. Thylakoids or baggy trousers are membrane lined flattened sacs. Thylokoids (or granna) contain chloroplast proteins, photosynthetic pigments and other factors required for photosynthesis.

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:

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