• C. CAM plant
• D. C₂​ plants

Answer 1

The correct option is A

C₄ plants

The correct option is A.

Explanation of the correct option:

1. C₄ cycle is also referred to as Hatch and Slack pathways.
2. In this pathway the initial fixation of carbon takes place in the mesophyll cells and the Calvin cycle occurs in the bundle sheath cells.
3. In C₄ plants, there is a specialized arrangement in leaves. The mesophyll cells are clustered around the bundle-sheath cells in a wreath or ring-type arrangement.
4. Example of C₄ plants - maize, sugarcane.

Explanation for the incorrect options:

_{Option B:}

In C₃ plants, the leaves do not show any Kranz anatomy.

Example - rice, wheat, cotton, etc.

Option C:

CAM stands for Crassulacean Acid Metabolism are the plants that are adapted to survive in arid climates.

Example - cactus, orchids, etc.

Option D:

C₂ cycle is also known as the oxidative photosynthetic cycle which takes place in the chloroplast, peroxisome, and mitochondria.
