Question
In 
-plants the bundle sheath cells
- Have thin walls to facilitate gaseous exchange
- Have large intercellular spaces
- Are rich in PEP carboxylase
- Have a high density of chloroplasts
The correct answer is: Have a high density of chloroplasts
The leaves of -plants have Kranz anatomy. In the leaf, vascular bundle is surrounded by bundle sheath and mesophyll cells. The bundle sheath consists of thick walled cylindrical cell. The chloroplasts of bundle sheath are larger than mesophyll cells. Most of the PEP carboxylase occurs in mesophyll cells, while most of ribulose 1-5 diphosphate carboxylase and malic enzyme in bundle sheath cells.
