COMEDKCOMEDK 2015Sexual Reproduction in Flowering Plants
Solution:
Dioecious plants are the unisexual plants which bear either male or female flowers, e.g., papaya, date palm etc. These plants prevent self pollination and encourage cross pollination. Both autogamy (transfer of pollen grains from the anther of a flower to the stigma of same flower) and geitonogamy (transfer of pollen grains from the anther of a flower to the stigma of another flower belonging to either the same plant or genetically similar plant) are the types of self 1 pollination and thus are prevented in case of dioecious plants.
