Vedclass · Answer

(B) In angiosperms,the pollen grain represents the male gametophyte. In about $60\%$ of angiosperms,pollen grains are shed at the $2$-celled stage (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,resulting in a $3$-celled stage. Therefore,the male gametophyte is shed at either the $2$-celled or $3$-celled stage. Among the given options,the $3$-celled stage is the correct developmental stage for shedding.

In angiosperms,the male gametophyte is shed at which stage?
