Vedclass · Answer

(A) In dioecious plants,male and female flowers are present on different plants. Since the male and female reproductive structures are physically separated on distinct individuals,self-pollination cannot occur. Autogamy (transfer of pollen grains from the anther to the stigma of the same flower) is prevented because the plant is unisexual. Geitonogamy (transfer of pollen grains from the anther of one flower to the stigma of another flower on the same plant) is also prevented because there is only one sex per plant. Therefore,dioecious plants prevent both autogamy and geitonogamy.
