Question

In which of the following plants are both male and female flowers born on the same plant, and the mode of pollination can be geitonogamy or xenogamy?

• A. Papaya
• B. Date Palm
• C. Maize
• D. Spinach

Hint:

Keep in mind:
Papaya and Date Palm are dioecious (with separate male and female plants).
Monoecious plants, like maize, have both male and female flowers on the same plant, which facilitates both geitonogamy and xenogamy.

Answer 1

The Correct Option is C

Plants that bear both male and female flowers on the same plant are called monoecious plants. Maize is an example of a monoecious plant.
Geitonogamy refers to the transfer of pollen between flowers on the same plant.
Xenogamy refers to the transfer of pollen between flowers of different plants. Maize exhibits both types of pollination.
