Question

Define pollinations. Explain wind and water pollination with example.

Answer 1

The process of transfer of the pollen from the anther to the stigma is known as pollination. Anemophily or wind pollination is a form of pollination whereby pollen is distributed by wind. Almost all gymnosperms are anemophilous, as are many plants in the order poales, including grasses, sedges and rushes. Other common anemophilous plants are oaks, sweet chestnuts, alders and members of the family Juglandaceae (hickory or walnut family).
1. Have brightly coloured petals to attract insects
2. Have a strong smell to attract insects
3. Usually contain nectar to attract insects
Water pollination is also termed as hydrophily and mode of pollination is water. It is quite rare in flowering plants and is limited to about 30 genera, mostly monocotyledons.
Example: Vallisneria, Hydrilla
