Cleistogamous flower

Vedclass · Answer

(C) Cleistogamous flowers are those that do not open at all. In these flowers,the anthers and stigma lie very close to each other. 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-pollination landing on the stigma.

In this type of flower,pollination occurs before the flower opens.
