Question
Cross pollination can occur in the following _______ except
Correct Answer
Option C is the correct answer.
Detailed Explanation
Protogyny (female parts mature first), dioecious plants (separate male and female plants), and protandry (male parts mature first) are all mechanisms that promote cross-pollination. Monoecious plants have both male and female flowers on the same plant, allowing for self-pollination in addition to cross-pollination, thus it is not exclusively a 'cross-pollination promoting' condition in the same way the others are.
Hint
Which term describes a plant where both male and female reproductive structures are on the same individual, allowing for self-pollination?
