Botany - Sexual Reproduction in Flowering Plants Question with Solution | TestHub

Geitonogamy is pollination where the transfer of pollen grains from the anther to the stigma of another flower of the same plant. Although geitonogamy is functionally cross-pollination involving a pollinating agent, genetically it is similar to autogamy since the pollen grains come from the same plant.
The dioecious plant has unisexual flowers and hence these plants neither exhibit autogamy nor geitonogamy.
