Question

What are Cleistogamous flowers? Can cross pollination occur in cleistogamous flowers? Give reasons for your answer.

Answer 1

Answer:

Chasmogamous flowers have exposed anthers and stigmata similar to the flowers of other species. Cross-pollination cannot occur in cleistogamous flowers. This is because cleistogamous flowers never open at all. Also, the anther and the stigma lie close to each other in these flowers.

Answer 2

Answer:

Chasmogamous flowers are the flowers that have open petals such that the reproductive organs are exposed to allow cross-pollination.Cleistogamous flowers are small, closed flowers with unexposed reproductive organs. Therefore, they cannot undergo cross-pollination. However, they undergo self-pollination since the stigma and anther are present near each other.
