Pollen grains are shed at the double-celled stage in most flowering plants. Stigma occurs in the growth of male gametophytes. Pollen grain gives rise to the pollen tube that absorbs nourishment for its production from the style cells.Pollen tube contains two cells generative cell and vegetative cell. Generative cells divide forming two male gametes, one fuses to form a diploid zygote with the egg, and the second male gamete fuses with with the two haploid polar nuclei to form primary endosperm nucleus . In the same embryo sac, these two actions of fertilization occur and are referred to as double fertilization.
