After the pollination how does fecundation occur in angiosperms? In these plants is fecundation dependent on water?
After the pollination one of the sperm nuclei from the pollen tube unites with the oosphere of the embryonic sac forming the diploid (2n) zygote. The erstwhile sperm nucleus fuses with the polar nuclei of the embryonic sac originating a triploid (3n) cell that by mitosis will turn into the secondary endosperm of the seed. The synergids as well as the antipodal cells degenerate after the fecundation process.
Fecundation in the plants is independent from water.
