Question
Which among the following statements are true for unisexual flowers?I. They possess both stamen and pistil.II. They possess either stamen or pistil.III. They exhibit cross-pollination.IV. Unisexual flowers possessing only stamens cannot produce fruits.I and IVII, III and IVIII and IVI, III and IV
Solution
The correct answer is II, III and IV.
Here's why:
I. Unisexual flowers do not possess both stamen and pistil. They have either one or the other, not both. So, this statement is false.
II. This statement is true. Unisexual flowers possess either stamen (male reproductive organ) or pistil (female reproductive organ).
III. This statement is also true. Since unisexual flowers have only one type of reproductive organ, they rely on cross-pollination for reproduction.
IV. This statement is true as well. Unisexual flowers that possess only stamens (male parts) cannot produce fruits because fruit production requires a pistil (female part).
