Question

how is pollination carried out by insects wind and water? explain
​

Answer 1

Answer:

Pollen grains are also adapted for insect pollination. ... The anthers dangle in the breeze, and the pollen is blown away. The pollen grains are very small and light so they are easily carried on the wind. A lot of pollen is produced, which increases the chances of a pollen grain reaching the stigma in another flower.

Answer 2

Answer:

This is called surface hydrophily, but is relatively rare (only 2% of pollination is hydrophily). This water-aided pollination occurs in waterweeds and pondweeds. In a very few cases, pollen travels underwater. Most aquatic plants are insect-pollinated, with flowers that emerge from the water into the air.
