What is the role of large bundle shealth cells found around the vascular bundles in

{C}_{4}

plants?

Options

ATo increase the number of chloroplast for the operation of Calvin cycle
BTo enable the plant to tolerate high temperature
CTo protect the vascular tissue from high light intensity
DTo provide the site for photorespiratory pathway

Correct answer

A. To increase the number of chloroplast for the operation of Calvin cycle

Step-by-step solution

C₄ plants show:

Chloroplast dimorphism.
Presence of Kranz anatomy.
Two times carboxylation process.
No photorespiration.

The large bundle sheath cells around the vascular bundles in the ${C}_{4}$ plants have numerous chloroplasts for the operation of calvin cycle.
