Question

In Kranz anatomy, the bundle sheath cells have

• A. thin walls, many intercellular spaces and no chloroplasts.
• B. thick walls, no intercellulai spaces and large number of chloroplasts.
• C. thin walls, no intercellular spaces and several chloroplasts.
• D. thick walls, many intercellular spaces and few chloroplasts.

Answer 1

Answer: (B)

thick walls, no intercellulai spaces and large number of chloroplasts.

Answer 2

The correct answer is option B , thick walls, no intercellulai spaces and large number of chloroplasts.

The C4 plants that are adapted to dry tropical regions have greater productivity of biomass. They possess a special type of leaf anatomy which is known as Kranz anatomy. The bundle sheath cells, in such anatomy, form several layers around the vascular bundles. These cells are characterized by having a large number of chloroplasts, thick walls impervious to gaseous exchange, and no intercellular spaces.

Therefore, In Kranz's anatomy, the bundle sheath cells have thick walls, no intercellulai spaces and large number of chloroplasts.
