it means that
generally pollengrain has two cells one vegetative and the other generative
so in many of the angiosperms about 60% of them she'd off from anther at this two celled stage
and in remaining 40% of angiosperms the generative cell divides into two cells called as male gamets when present in the anther and at this three celled stage of the pollen grain they she'd out..... three cells means vegetative ,two male gamets
