Question

Which of the following is not an unisexual flower?

A. Coconut

B. Papaya

C. Gulmohor

D. Maize

Answer 1

Hint: Unisexual flowers are those which either have stamens or carpels. They do not possess both of them else they will be called bisexual flowers.

Complete step by step answer:

Let’s discuss the options and find out the correct answer.

- Coconut is a unisexual flower as it contains either the male or female reproductive parts. It does not depend on the carpel to pollinate. It has only one stamen.

- Papaya pollinators need to collect pollen from male flowers, return to female flowers to ensure pollination and fruit development. Since the papaya tree can be male, female or hermaphrodite, the pollen can be carried either by wind or insects or air to confirm pollination and develop the fruit.

- Some flowers possess both male and female reproductive parts, they are known as bisexual flowers. Gulmohor is one such plant containing both gynoecium and androecium.

- Maize, also called Corn in some parts of the world, is pollinated by wind. The male anthers release pollen and it flies away to a female corn flower nearby. Most of the flowers contain either male or female parts rather than some flowers which have both of them.

Hence, option C: Gulmohor is the correct answer.

Note: Unisexual plants undergo sexual reproduction through pollination. In this reproduction, two parents are required. The offspring have properties of both the parents.
