Running head: POLLINATION
Pollination, its importance to the environment and its significance
Pollination is the process whereby pollen grains from the anthers are transferred to the
stigma of a flower with the aim of fertilization. A flower is made of the male part known as the
stamen, which comprises of the anthers and the filament, and the female part known as the pistil,
which comprises of the stigma, style, and the ovary. The main function of the anthers is to
produce pollen grains while the filament holds the anthers in position. On the other hand, the
main role of the stigma is to receive pollen grains from the anthers, the style holds the stigma and
also encourages the transfers of pollen grains to the ovary, via the pollen tube, where fertilization
takes place with mature ovules.
Pollination can take place in two different ways that are either through cross-pollination
or self-pollination. Cross pollination involves the transfer of pollen grain to the stigma of a
different mature flower with the aid of either wind or animals. Self-pollination, on the other
hand, involves the transfer of pollen grains from the anther...
