Question

Advantage of cleistogamy is

• A. Vivipary
• B. Higher genetic variability
• C. More vigorous offspring
• D. No dependence on pollinators

Answer 1

The Correct Option is D

In cleistogamous flowers, anthers and stigma lie close to each other. When anthers dehisce in the flower buds, pollen grains come in contact with the stigma to effect pollination. Thus, these flowers produce assured seed set even in the absence of pollinators. The higher genetic variability and more vigorous offsprings are the produced to variations obtained by sexual reproduction. Vivipary relates to the birth of young babies from mammals.
