Question

In $C_4$-plants, photosystem II is absent in chloroplasts of

• A. Mesophyll cells
• B. Bundle sheath cells
• C. Palisade cells
• D. Spongy cells.

Answer 1

The correct option is B Bundle sheath cells

$C_4$ plants have two types of photosynthetic cells, mesophyll and bundle sheath cells. Mesophyll chloroplasts are randomly distributed along cell walls, whereas bundle sheath chloroplasts are located close to the vascular tissues or mesophyll cells depending on the plant species. The photosystem is absent in bundle sheath cells.
