Q. The main advantage of Cleistogamy is that it ensures

UP CPMTUP CPMT 2015Sexual Reproduction in Flowering Plants

Solution:

In cleistogamy (Kleistos - closed, gamos -marriage), the flowers are intersexual and remain closed always resulting in self-pollination. In cleistogamous flowers, the anthers dehisce inside closed flowers. Growth of style brings the pollen grains in contact with stigma. Pollination and seed set are assured even in the absence of pollinators.
