Question:

Autogamy can occur in a chasmogamous flower if

Options:

1. pollen matures before maturity of ovule
2. ovules mature before maturity of pollen
3. both pollen and ovules mature simultaneously
4. both anther and stigma are of equal lengths

Solution:

Autogamy is a method of self-pollination in which the stigma of a flower receive pollens from the anther of same flower. For autogamy, both sex organs of a chasmogamous flower should mature at the same time. As chasmogamous flowers open at maturity, pollen release and stigma receptivity should be synchronised for the process of autogamy. In such flowers, the length of anther and stigma plays secondary role in autogamy. e.g., in case of protandry (pollens mature early) and protogyny (stigma matures early) leads to cross-pollination.
