Question

Agranal chloroplasts are found in:

• A. Mesophyll of pea leaves
• B. Bundle sheath of mango leaves
• C. Mesophyll of maize leaves
• D. Bundle sheath of sugarcane leaves

Answer 1

The correct option is D Bundle sheath of sugarcane leaves

Two types of cells are found in $C_4$ plants for photosynthesis - mesophyll cells of $C_4$ plants exhibit grana, but the bundle sheath cells of $C_4$ plants have agranal chloroplasts. Maize is a $C_4$ plant and the mesophyll of maize contains granal chloroplasts. Sugarcane is a $C_4$ plant and the bundle sheath of sugar cane leaves contains agranal chloroplasts.

Pea and mango are $C_3$ plants which contain granal chloroplasts.
