<P> Pollination is the process by which pollen is transferred to the female reproductive organs of a plant, thereby enabling fertilization to take place . Like all living organisms, seed plants have a single major purpose: to pass their genetic information on to the next generation . The reproductive unit is the seed, and pollination is an essential step in the production of seeds in all spermatophytes (seed plants). </P> <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>
