The biological function of a flower is to facilitate reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) resulting from cross pollination or allow selfing (fusion of sperm and egg from the same flower) when self pollination occurs. Pollination have two types which is selfpollination and crosspollination. Selfpollination happens when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Crosspollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species. Selfpollination happened in flowers where the stamen and carpel mature at the same
