The transfer of pollen from the anthers of a flower to the stigma of the same
flower or of another flower. Pollination is a prerequisite for
fertilization: the fusion of nuclei from the pollen
grain with nuclei in the ovule. Fertilization allows
the flower to develop seeds.
Some flowers will develop seeds as a result of self-pollination , when pollen and pistil are from the same plant, often (but not always) from the same flower. Other plants require cross-pollination: pollen and pistil must be from different plants.
