During self-pollination, a plant transfers pollen from its anther to its stigma to complete the cycle of pollination. While some plants have female and male flowers and can self-pollinate, other plants grow as either a male or female plant. In cross-pollination, a plant is fertilized by receiving pollen from the stigma of another plant to develop fruit and seeds. A plant that is cross-pollinated cannot grow and mature on its own, because it must receive pollen from another plant. Most cross-pollinated plants are pollinated by bees.

___________________________________________________________________
- SELF POLLINATION :
★ It is the transfer of the pollen grains from the anther of the flower to the stigma of the same or another flower on the same plant.
★ Occurs only in perfect flowers.
★ Transfers few numbers of pollen.
★ It results in homozygous offspring.
- CROSS POLLINATION :
★ It is the transfer of the pollen grains from the anther of a flower to the stigma of another flower on a different plant of the same species.
★ Occurs both in perfect or imperfect flowers.
★ Transfers large numbers of pollen.
★ It results in heterozygous offspring.
