Question

Contrivances for self pollination are

• A. Bisexuality
• B. Homogamy
• C. Cleistogamy
• D. All of the above

Answer 1

The correct option is D All of the above

Flowers by nature are mostly cross pollinated. There are various adaptations for this process. In unisexual and bisexual flowers, certain devices are present for the effective self pollination and avoiding cross pollination, which are called as contrivances of self pollination. They are: bisexuality- both male and female sex organs in single flower, homogamy- inbreeding and cleistogamy- propagation using non-opening, self pollinating flowers.

Thus, the correct answer is option D.
