Angiosperm Reproduction

The process of sexual reproduction in flowering plants is known as angiosperm reproduction. In flowering plants, reproduction begins with pollination, or the transfer of male gametes (pollen) from the male reproductive organ (anther) to the female reproductive organ (pistil), and ends with fertilization of the female gametes (egg), which produces a zygote, which then grows to become a mature plant.
