Answer the question by selecting the appropriate option given below.

Assertion A: Pollination is the transfer of pollen grains from anther to stigma

       2. Reason R: Pollination is done by some agents like water, birds and insects.​

Answer 1

Explanation:

Wind-pollinated flowers need to produce great quantities of pollen to be sure that at least some pollen grains will reach the stigmas of other flowers.These flowers are often small and inconspicuous since they do not need to attract insects. They do not produce nectar and they do not have any scent. Most trees and grasses have wind-pollinated flowers. Cross-pollination occurs when pollen is transferred from the anthers of one flower to the stigma of another flower. Self-pollination occurs when the pollen from the anther of a flower is transferred to the stigma of the same flower. Cross-pollination is better than self-pollination. When flowers are cross-pollinated their seeds germinate into strong, healthy plants. Seeds from self-pollinated flowers produce weaker, less healthy plants.
