Question

Wall of a mature pollen grain consists of:

• A. Ektexine and endexine
• B. Tapetum and endothecium
• C. Exine and intine
• D. Foot and baculate layer

Answer 1

The correct option is C Exine and intine

• The pollen wall actually is the multi-layered structure that includes an inner intine, which is composed mainly of polysaccharides, and an outer exine, which consists mainly of sporopollenin.
• The exine is further divided into two layers, the outer ektexine (sexine and foot layer) and the inner endexine.

So the correct answer is C.
