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:

Monoecious plants like maize can exhibit both self-pollination (geitonogamy) and cross-pollination (xenogamy).

Answer 1

The Correct Option is C

In maize, both male (tassel) and female (ear) flowers are found on the same plant — making it monoecious.
Pollination can occur between flowers of the same plant (geitonogamy) or between different plants (xenogamy).
Therefore, maize fits the criteria given.
