Question

Which of the following is not an adaptation for anemophily ?
(1) Presence of well exposed stamens
(2) Often presence of single ovule in an ovary
(3) Sticky pollen grain
(4) Large and often feathery stigma​

Answer 1

Answer:

3 Sticky pollen grain

Explanation:

The statement not correct with respect to Anemophily is pollen grains are light and sticky.

Anemophily or wind pollination is a form of pollination whereby pollen is distributed by wind. Anemophilous pollen grains ace light and non-sticky so that they can be transported by air currents. They often possess well-exposed stamens and large feathery stigma to easily trap airborne pollen grains. Wind pollinated flowers packed into an inflorescence. Wind pollination is quite common in grasses. It is more common amongst abiotic pollination.

Answer 2

The correct option is (3) Sticky pollen grain.

• Anemophily is the type of pollination where pollination of flowers by pollen grains occurs by air.
• For pollination by air, pollen grains must be lightweight and non-sticky so that can freely move in the air.
• Flowers with large and feathery stigma is also necessary for pollination to occur because such plant can easily trap pollen grains from the air.
• Wind pollinated plants usually have a single ovule in an ovary and are commonly seen in the grass.
• Sticky pollens are a feature of insect-pollinated plants.
