Vedclass · Answer

(C) Cleistogamy is a condition in which 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. The primary advantage of this mechanism is that it ensures seed set even in the absence of pollinators.
