`C_(4)` plants are more efficient in photosynthesis than `C_(3)` plants due to

Options

A. higher leaf area
B. presence of larger number of chloroplasts in the leaf cells
C. presence of thin cuticle
D. lower rate of photorespiration

Answer

B

Explanation

`C_(4)`-plants are more efficient in photosynthesis than `C_(3)`-plants but use more energy. They possess the larger number of chloroplasts in the leaf cells. In thhe leaves of `C_(4)`-plants, the vascular bundles are surrounded by bundle sheath cells which in turn are surrounded by mesophyll cells. Chloropplast in bundle sheath cells are larger and always contain grana, whereas chloroplasts in mesophyll cells are smaller.
