Question

Which one of the following is not correct about pollen grains?

• A. Male gametophyte
• B. Exine and intine wall layers
• C. Generative nucleus as gamete
• D. Pollen tube formed by the intine wall layer

Answer 1

Answer: (C)

Generative nucleus as gamete

The pollen grain is the male gametophyte which contains the male gametes. The pollen grain is surrounded by two layers as exine which forms the outer layer and intine which forms the inner layer. The generative cell divides to form the two male gametes. The intine layer comes out of the germ pore to form the pollen tube.

Thus, the correct answer is option C.
