What is the term for the process in which pollen is transferred from the anther of one flower to the stigma of a different plant?

Explanation

Cross-pollination, also known as allogamy, refers to the transfer of pollen grains from the flower of one plant to the stigma of another, promoting genetic diversity. Self-pollination (autogamy) occurs within the same flower. Polygamy and cleistogamy refer to different reproductive strategies.
