Question

How do insects help in pollination?

Answer 1

Pollination:

1. Pollination is the transfer of pollen grains to the ovary of the plant.
2. Pollination by insects is called entomophily.
3. Pollination by insects happens when insects go in search of food. Flowers produce a sugary liquid called nectar which many insects consume on a large basis. When insects land on a flower, pollen grains tend to stick to their bodies.
4. The insect then moves from one to another flower of the same species, pollen gets transferred to the stigma of flowers and hence causing pollination.

Therefore pollination by insects occurs when insects move from one plant to another in search of food.
