Question

Identify the similarity between wind and water pollinated flowers.

Easy

A

Both have sticky pollen grains.
B

Both are not very colourful and do not produce nectar.
C

Both have large feathery stigma with single ovule in the ovary.
D

Both produce pollen grains that are protected by a mucilaginous covering.

Solution

Both wind and water pollinated flowers are not very colourful and do not produce nectar. This is because colour is to attract biotic pollinators and nectar acts as a floral reward so that the pollinators keep visiting the plant and help in pollination. Abiotic agents neither needs to be attracted nor need any floral reward.
