Open in App
Solution
The correct option is B Cleistogamy
- Cleistogamy is also called as self-pollination, which describes the trait of certain plants to propagate by using self-pollinating flowers. It takes place only in bisexual flowers.
- The principal advantage of cleistogamy is that it requires fewer plant resources to produce seeds because the development of petals, nectar and large amounts of pollen are not required.
- This efficiency makes cleistogamy particularly useful for seed production on unfavorable sites or adverse conditions.
- Cross-pollination in crop plants is known as Allogamy. Protandry is a condition in which stamens mature earlier than pistils which also prevents self-pollination.
- Protogyny refers to the development and maturation of female reproductive parts before that of male parts of the flower to prevent self-pollination.
Thus, the correct answer is option B.
