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

Answer 1

The correct option is A

thick walls, no intercellular spaces and a large number of chloroplasts

The correct option is A.

Explanation for correct option:

1. Kranz anatomy of leaves is found in C₄​ plants.
2. Here, mesophyll cells are clustered around the bundle-sheath cells in a ring-like fashion.
3. The bundle sheath cells with thick walls and no intercellular spaces between them prevent the entry of O₂ and escape of CO₂.
4. It has a large number of chloroplasts.

Final Answer: So, the bundle sheath cells have thick walls, no intercellular spaces and a large number of chloroplasts
