Male gametophyte in angiosperms produces :

Step-by-step solution

In Angiosperms, pollen grain is the first male gametophyte. Microspore divides mitotically forming two cells. 1. Vegetative cell: Bigger in size having abundant food reserve and large irregularly shaped nucleus. 2. Generative cell: Small and floats in the cytoplasm of the vegetative cell. It is spindle-shaped with dense cytoplasm and nucleus. Shedding of pollen grains takes place at this two-celled stage in 60 % of angiosperms. In rest, the generative cell divides to form the male gametes (sperms) and pollen is she
