Answer:
Both autogamy and geitonogamy are prevented in 3)Date palm.
Explanation:
What is Autogamy?
Autogamy is the method of self-pollination in which the pollen of a flowering plant fertilizes the female gamete or the ovum of the same flower.
What is Geitonogamy?
Geitonogamy is the method of self-pollination in which the pollen of a flowering plant fertilizes the female gamete or the ovum of another flower on the same plant or flower of a genetically identical plant.
Among the given plants, maize, wheat, and castor are monoecious meaning a plant has both the pistillate flowers and the staminate flowers. Therefore, they can self-pollinate.
The date is a dioecious plant meaning one plant is either male or female. Hence, self-pollination is prevented.
Therefore, both autogamy and geitonogamy are prevented in 3)Date palm.
