Question

In $C_4$ plants, the bundle sheath cells:

• A. Have thin walls to facilitate gaseous exchange
• B. Have large intercellular spaces
• C. Are rich in PEP carboxylase
• D. Have a high density of chloroplasts

Answer 1

The correct option is D Have a high density of chloroplasts

A layer of cells surrounding the vascular bundle is the bundle-sheath cells. They are present in C${}_4$ plants. They have large number of chloroplasts. The bundle-sheath cells have thick-walled impervious to gaseous exchange and no intercellular spaces.

PEP carboxylase is present in mesophyll cells.
