▪▪On division, the generative cell is to form two male gametes. In a 3 celled pollen, the generative cell has already divided into two male gametes, so that no further division occurs in the pollen tube.

HLO MATE HERE IS UR ANSWER

. In majority of angiosperms , the pollen grains are shed at two celled stage.

. They are vegetative cell and generative cell.

. After pollination , in thr pollen tube the generative cell divides to give rise to two male gamets .

But in some angiosperms , the pollen grains are shed at three celled stage.

. This is because the generative cell divides to give rise to two male gametes before pollination.
