Castor and maize

Vedclass · Answer

(C) Outbreeding devices are mechanisms that promote cross-pollination. Monoecious plants,such as $Castor$ and $Maize$,possess both male and female flowers on the same plant. In these plants,the presence of unisexual flowers prevents autogamy (transfer of pollen from the anther to the stigma of the same flower) because the flower is either staminate or pistillate. However,geitonogamy (transfer of pollen from the anther of one flower to the stigma of another flower on the same plant) can still occur because both types of flowers are present on the same individual. Therefore,$Castor$ and $Maize$ are the correct examples.
