Question

Carbon assimilation occurs in bundle sheath cells of

• A. CAM plants
• B. C${}_4$ plants
• C. C${}_3$ plants
• D. All of the above

Answer 1

Answer: (B)

C${}_4$ plants

In \text C_4C4​ plants, the light-dependent reactions and the Calvin cycle are physically separated, with the light-dependent reactions occurring in the mesophyll cells (spongy tissue in the middle of the leaf) and the Calvin cycle occurring in special cells around the leaf veins. These cells are called bundle-sheath cells.

So, the correct option is 'Option B'.
