Question

In $C_4$ plants, bundle sheath cells

• A. are rich in PEP carboxylase
• B. lack RuBisCO
• C. lack both RuBisCO and PEP carboxylase
• D. are rich in RuBisCO

Answer 1

The correct option is D are rich in RuBisCO

In $C_4$ plants, bundle sheath cells are rich in RuBisCO. These cells form several layers around the vascular bundles. They are characterized by a large number of chloroplasts, thick walls and do not allow gaseous exchange to take place. They have no intercellular spaces. The Calvin cycle takes place in these cells in $C_4$ plants.
