Male gametophyte in angiosperms produces
Two sperms and a vegetative cell
Single sperm and a vegetative cell
Single sperm and a two vegetative cells
Single sperm and a two vegetative cells
A.
Two sperms and a vegetative cell
Pollen grain or male gametophyte in angiosperms contain one generative cell. The generative cell. The generative cell further divides mitotically to form two male gametes(sperms). So, a mature male gametophyte in angiosperms contains two sperms and one vegetative cell.
