Vedclass · Answer

(A) The correct answer is $Commelina$. $Commelina$ produces two types of flowers: chasmogamous flowers (which are open) and cleistogamous flowers (which remain closed). Cleistogamous flowers do not open at all,and 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. These flowers produce assured seed-set even in the absence of pollinators.
