NEET BIOLOGY

Detailed explanation-1: -State TRUE or FALSE: Wind, water, and animals are the different agents of pollination. Answer: Wind, water, animals and insects are the different agents of pollination.

Detailed explanation-2: -I) Both wind and water pollinated flowers are very colourful and produce nectar. II) Wind-pollinated flowers have large feathery stigma to easily trap air-borne pollen grains. III) Flies are the dominant biotic pollinating agents.

Detailed explanation-3: -Pollen grains are very small and light. As such, pollen grains can easily float in the air and get transferred from the anther to the stigma within the same flower or even other flowers of the same species. So, wind is a major and good agent of pollination. Q.

Detailed explanation-4: -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. 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.
