WebThe angiosperm female gametophyte is critical to the reproductive process. It is the structure within which egg cell production and fertilization take place. In addition, the female gametophyte plays a role in pollen tube guidance, the induction of seed development, and the maternal control of seed development. WebThe male gametophyte containing the generative cell splits into two sperm nuclei, one of which fuses with the egg, while the other degenerates. After fertilization of the egg, the diploid zygote is formed, which divides by mitosis to form the embryo. WebThe male gametophyte in angiosperms is the microgametophyte (pollen grains), which develops within the anther and consists of two sperm cells surrounded within a vegetative cell in the anthers of the stamens. current bank bank statement
