Question

why are cliestogamous flowers invariably autogamous?​

Answer 1

Ello user !!!!!!!!!

Here is your answer,

=============================================

The pollination that occurs in opened flowers is called chasmogamy.

When anthers dehisces in the flower buds, pollen grains come in contact with the stigma for effective pollination.

Thus, these flowers are invariably autogamous as there is no chance of cross-pollen landing on the stigma.

HOPE THIS HELPS YOUU :)
