Vedclass · Answer

(C) In $60\%$ of angiosperms, pollen grains are shed at the $2$-celled stage, consisting of a vegetative cell and a generative cell.In the remaining species, the generative cell divides mitotically to give rise to the two male gametes before pollen grains are shed.Therefore, the pollen grains are shed at the $3$-celled stage (one vegetative cell and two male gametes) in these species.Thus, the male gametes are formed in the $3$-celled stage of the pollen grain.

In which stage of the pollen grain are the male gametes formed?
