What Is The Difference Between Self Pollination And Cross Pollination

In self pollination pollen grains from the anther of the similar plant are shed upon the stigma surface whereas in cross pollination the transfer of pollen to the stigma of a flower of a different plant of the same species or different species takes place.

In self pollination both the stigma and anther simultaneously mature. For cross pollination to happen the flower should be open. Cross pollination is defined is defined as the deposition of pollen grains from anther of a flower to the stigma of a different flower of another plant of same or different species. Transfers large numbers of pollen.

Self pollination is the transfer of pollen grains from the anther to the stigma of the same flower. The key difference between self pollination and cross pollination is that the self pollination is the deposition of pollens of a flower on the stigma of the same flower while cross pollination is the deposition of the pollen of a flower on the stigma of a different flower of the same plant or a different plant of the same species. Self pollination occurs in perfect flowers only and the plants have small flowers while cross pollination occurs in both imperfect and perfect flowers and the flowers of the plants have the scent nectar and bright colored petals. In cross pollination both the stigma and anther mature at different times.

Cross pollination is the transfer of pollen grains from the anther of a flower to the stigma of a flower of a different plant of the same species. Self pollination is the transference of the pollen grains from the anther to the stigma of either the same or genetically similar flower.
