Question

Assertion (A): Sugars are synthesized in the bundle sheath cells of maize plants.

Reason (R): Calvin cycle occurs in the bundle sheath cells of $C_4$ plants.

• A. Both A & R are true and R explains A
• B. Both A & R are true and does not explain A
• C. A is true and R is false
• D. Both A & R are false

Answer 1

The correct option is A

Both A & R are true and R explains A

Bundle sheath cells of $C_4$ plants possess RuBisCo and obtain $C{O}_2$ through the Hatch-Slack pathway from the mesophyll cells. This $C{O}_2$ is accumulated at high concentrations in the bundle sheath cells and is fixed to form sugars through the Calvin cycle.
