Q. In which of the following type of pollination, flowers have pollen grains that are light and non-sticky while stigma is large and often feathery?

Solution:

Pollination by wind is known as anemophilous and is the more common amongst abiotic pollinations. Wind pollination requires the pollen grains to be light and non-sticky so that they can be transported in wind currents. They often possess well-exposed stamens and large often-feathery stigma
to easily trap airborne pollen grains. Wind pollinated flowers often have a single ovule in each ovary and numerous flowers packed into an inflorescence; a familiar example is the corn cob-the tassels. In maize, pollination is going to happen through the agency of wind.
