Pollination is the transfer of pollen ( Which contains the male sex cells) from anther (part of female reproductive organ) to stigma (part of female reproductive organ). This process proceeds fertilization. Pollination may occur with the same flower (Self pollination) or between flowers of different plant of same species (cross pollination). In most plants pollination is carried out either by insects (entomophilous pollination) or by wind ( anemophilous pollination). Less commonly birds, bats or water are the agents of pollination. Insect pollinated flowers are typically bright coloured, scented, and produce nectar, on which insects feed. Such flowers also tend to have that patterns that are only visible to Ultraviolet light, which may insects can see but animals can't. These features attract insects, which become covered with the sticky or hooked pollen grains, when they visit one flower, and then they transfer pollen grains to the next flower they visit. Wind pollinated flower are generally small, relatively inconspicuous and unscented. They produce large quantities of light pollen grains that are easily blown by wind d to other flowers.
