specialized granules responsible for colouration of cells
structures responsbile for organizing the shape of the organism
inclusion bodies lying free inside the cells for carrying out various metabolic activities
internal membrane systems that may become extensive and complex in photosynthetic bacteria

Hide Solution

Verified By Collegedunia

The Correct Option is D

Solution and Explanation

In some prokaryotes like photosynthetic bacteria and blue-green algae possess small member lined chromatophores which is similar to but chemicaly simpler than the chlorophyll of 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)
