Solution:

A pollen grain represents the male gametophyte. It has two cells, the generative cell and vegetative cell. The generative cell divides mitotically and gives rise to two male gametes before pollen grains are shed. Egg cell present in embryo sac is the female gamete that fuses with one male gamete to form zygote.
