Answer 1

What are chasmogamous flowers? Can cross-pollination occur in deistogamous flowers? Give reasons for your answer

Ans: Chasmogamous flowers are those flowers which are open with exposed anther and stigma.

Cleistogamous flowers are those flowers which do not open at all. In these flowers, the anthers and stigma lie close to each other, when anthers dehisce in the flower buds, the pollen grains come in the contact with stigma to effect pollination. So these flowers are invariably self-pollinated as the flowers remain closed and there is no chance of cross pollen landing on the stigma. Pollination and seed setting are assured even in the absence of pollinators
