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 flower possessing only stamens cannot produce fruits

(a) (i) and (iv)
(b) (ii), (iii) and (iv)
(c) (ii) and (iii)
(d) (i), (iii) and (iv)

Answer 1

(b) (ii), (iii) and (iv)

Unisexual flowers have either male or female sexual organ. Therefore, they cannot self-pollinate and, thus, show cross pollination. The ovary of the female organ develops into a fruit after fertilisation, therefore flowers having stamens cannot produce fruits.
