Question

Answer 1

Answer:

hasmogamous Flower: When a flower exposes its anthers and stigma, the flower is open to pollination from any other flower. This condition is called chasmogamy and such a flower is called chasmogamous flower. Complete autogamy is rare in chasmogamous flower. Perfect synchronization between pollen release and stigma receptivity is required in such flowers to allow self-pollination.

n a normal flower which opens and exposes the anthers and stigma complete autogamy is rather rare. Majority of flowering plants produce hermaphrodite flowers and pollen grains are likely to come in contact with the stigma of the same flower. Continued self-pollination result in inbreeding depression.
