Question

Calvin cycle occurs in the bundle sheath cells of $C_4$ plants

• A. True
• B. False

Answer 1

The correct option is A

True

In C${}_4$ plants, oxaloacetic acid (OAA) is formed upon carbon fixation in mesophyll cells. The OAA is transported to bundle sheath cells, where it is reduced to malic acid. The malic acid undergoes decarboxylation and produces $C{O}_2$ and pyruvic acid. $C{O}_2$ is then fixed through Calvin cycle in the bundle sheath cells.
