The transfer of pollen grains from the male part of a flower, called the anther, to the female part of the same flower, called the stigma, is known as self-pollination. This process is also sometimes referred to as self-fertilization. During self-pollination, the pollen grains land on the stigma and begin to germinate, growing a tube down through the style to reach the ovary. This tube delivers the male gametes, contained within the pollen grains, to the female gametes in the ovules, resulting in fertilization and the production of seeds. Self-pollination is common in plants that have both male and female reproductive organs within the same flower. It is a mechanism that ensures that the plant can reproduce even if there are no other plants nearby for cross-pollination. Therefore, the transfer of ripe pollen grains from the anther to the stigma of the same flower is termed self-pollination.
