Very basic, put into layman's terms. However, there some inaccuracies. In actuality, during double fertilization, "the diploid central cells" are two, separate cells, not to two, sort of fused cells as depicted in this animation. In addition, there are other megasporangium that exist in the Embryo sac until double fertilization occurs. After d.f., those megasporangium are destroyed.
At what point does the microspore become known as the pollen grain? Is it as soon as the microspore mother cell has divided by meosis to produce the microspores, that they are considered pollen grains OR is it when division by mitosis occurs producing the generitive & tube cells enclosed by a thick, that it is considered to be a pollen grain.
@1091Floyd21 correct word is microsporocytes and that my friend is an immature sperm cell and is still being produced by the taptum. when they mature they become pollen grains which get disperses by wind or pollinators.
