Vedclass · Answer

(C) In angiosperms,the pollen grain represents the male gametophyte.At the time of shedding,most angiosperms (about $60\%$ of species) release pollen grains at the $2$-celled stage,consisting of a vegetative cell and a generative cell.However,in the remaining species,the generative cell divides mitotically to give rise to two male gametes before the pollen grains are shed.Therefore,the mature male gametophyte,at the time of fertilization,consists of $3$ cells: one vegetative cell and two male gametes.

The mature male gametophyte in angiosperms is typically composed of how many cells?
