(A) Cleistogamy is a phenomenon where flowers do not open at all. In such flowers,the anthers and stigma lie 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. $Commelina$ is a classic example of a plant that produces both chasmogamous (open) and cleistogamous (closed) flowers.
