Fecundation in angiosperms
After the pollination, explain how does the fecundation takes place within the angiosperms and whether fecundation depends upon the water?
Expert
After the pollination, one of sperm nuclei from the pollen tube joins the oosphere of embryonic sac making the diploid (2n) zygote. Other sperm nucleus fuses along with the polar nuclei of embryonic sac developing a triploid (3n) cell which through the mitosis will turn in the secondary endosperm of the seed. The antipodal cells and the synergids degenerate after the fecundation process completes. Fecundation within these plants is independent from the water.
