Question and Answer

The pollen grain is
(A) An immatures male gametophyte.
(B) A mature male gametophyte.
(C) Partially developed male gametophyte.
(D) Both (A) and (C)

Answer

Answer: D
Pollen grain is an immature male gametophyte as it has two cells out of which one develops into two male gametes after pollination. The generative cell of pollen undergoes mitosis to form two male gametes. So, pollen is a immature or partially developed male gametophyte. Correct answer is D.
