Vedclass · Answer

(B) In flowering plants (angiosperms),the pollen grains are shed at either a two-celled or a three-celled stage.In over $60\%$ of angiosperms,pollen grains are shed at the two-celled stage (one vegetative cell and one generative cell).In the remaining $40\%$ of angiosperms,the generative cell divides mitotically to give rise to the two male gametes before pollen grains are shed,resulting in a three-celled stage.

In $40\%$ of angiosperms,the pollen grains are shed at which stage?
