Answer» Solution :In over 66 percent of angiosperms, pollen grains are SHED at this 2 celled stage. Vegetative cell and generative cell. In REMAINING species, generative cell divides mitotically to give rise to the two male gemetes before pollen grains are fixed. Vegetative cell and two male gametes are in 3-celled stage. In 3 celled stage, pollen TUBE germinate on stigma and are produced from a germpore. The material of pollen grain COMES to pollen tube. Pollen tube proceeds in tissue of stigma with growth.
