<P> For the process of pollination to be successful , a pollen grain produced by the anther , the male part of a flower , must be transferred to a stigma , the female part of the flower , of a plant of the same species . The process is rather different in angiosperms ( flowering plants ) from what it is in gymnosperms ( other seed plants ) . In angiosperms , after the pollen grain has landed on the stigma , it creates a pollen tube which grows down the style until it reaches the ovary . Sperm cells from the pollen grain then move along the pollen tube , enter the egg cell through the micropyle and fertilise it , resulting in the production of a seed . </P>
