The process by which seed plants reproduce is called pollination. This occurs when pollen grains, which contain male gametes, are transferred from the male part of a flower (the anther) to the female part (the stigma). Following successful pollination, fertilization can occur, leading to the formation of seeds. Seed plants can reproduce through various methods, including wind, water, or animal-mediated transfer of pollen. This process is vital for the diversity of plant species, as it enables genetic variation and adaptation in changing environments.
