What Is The Difference Between Self Pollination And Cross Pollination

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.

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. For cross pollination to happen the flower should be open. 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. Self pollination can happen either in the same flower or another flower of the same plant while cross pollination can happen between two flowers on different plants.

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. In cross pollination both the stigma and anther mature at different times. Self pollination is the transfer of pollen grains from the anther to the stigma of the same flower. Transfers large numbers of pollen.

Self pollination is the transference of the pollen grains from the anther to the stigma of either the same or genetically similar flower. In self pollination both the stigma and anther simultaneously mature.
