Question

Which of the following characteristics is observed in wind pollinated flowers?

Easy

A

Pollen grains are long, ribbon like.
B

Pollen grains are sticky in nature.
C

Presence of large and often feathery stigma.
D

Flowers generally have a foul odour.

Solution

Wind pollination requires that the pollen grains are light and non-sticky so that they can be transported in wind currents. They often possess well-exposed stamens (so that the pollen is easily dispersed into wind currents) and large often-feathery stigma to easily trap air-borne pollen grains.
