Question

Which one shows dimorphic chloroplasts

• A. Mango
• B. Castor
• C. Banyan
• D. Amaranthus

Answer 1

The correct option is D Amaranthus

Mango, castor, and banyan are monomorphic chloroplasts but amaranthus shows dimorphic chloroplasts in above options. Amaranthus is the C${}_4$ plant which is found in tropical and subtropical regions, these plants show Kranz anatomy. The vascular bundles in C${}_4$ leaves are surrounded by a layer of bundle sheath cells that contain a large number of chloroplasts i.e., they are dimorphic. The chloroplasts of bundle cells are larger in size and are arranged centripetally while the mesophyll cells have the normal type of chloroplasts.
So, the correct option is D.
