______
▪▪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.
▪▪In two celled pollen grain, the generative cell descends in the pollen tube and division to form two male gametes.

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.
