flower is transferred to the stigma of the same flower.
4. Autogamy-It can be performed in three ways-
a.Homogamy- Anther and stigma mature at the same time, so that autogamy can takes place.
b.Cleistogamy-It is seen in those where flowers remain closed so that pollination can be performed within the same flower.
c.Chasmogamy-In this method of pollination, flowers are open but anther, stigma, and style show bending, folding, and growth such that autogamy can takes place.
