Question

Even in the absence of pollinating agents, seed set is assured in…………

• A. Cleistogamous flowers
• B. Bisexual
• C. Chasmogamouns flowers
• D. All of the above

Answer 1

The correct option is A Cleistogamous flowers

Cleistogamy is a type of automatic self-pollination of certain plants that can propagate by using non-opening, self-pollinating flowers.

When anthers dehisce in the flower buds, pollen grains come in contact with the stigma to effect pollination. Thus, cleistogamous flowers are invariably autogamous as there is no chance of cross-pollen landing on the stigma. Cleistogamous flowers produce assured seed-set even in the absence of pollinators.

Especially well known in peanuts, peas, and pansy this behavior is most widespread in the grass family. These flowers do not open hence they do not need any pollinator.

So, the correct answer is "cleistogamous flowers".
