Question

Define pollination. Explain water and wind pollination with examples.

Answer 1

Hint: Reproduction in flowering plants occurs in the flower part. It involves the transformation of diploid sporophytic cells into haploid gametophyte cells and leads to formation of zygote which grows as the plant body.

Complete step by step answer:
Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma. The goal of every living organism, including plants, is to create offspring for the next generation
Pollination in flowers occurs by two ways: Self pollination and cross pollination.
Self pollination: It is the process in which pollen grains are transferred from anther to stigma of the same flower or same genetically same flower. This is further two types: Autogamy and Geitonogamy.
Cross pollination: It is the process in which pollen grains are transferred from anther of the one plant to stigma of the other plant. This is further two types: Abiotic (Anemophily and Hydrophily) and biotic (Entomophily, Ornithophily and Chiropteropily).
Anemophily also known as wind pollination. It is a form of pollination by which pollen is distributed by wind. All gymnosperm squares measure anemophilous like several plants in the order poales (grasses, sedges and rushes). Another example of anemophilous plants are oaks, sweet chestnuts, alders and family of these plants Juglandaceae’.
Water pollination is also called hydrophily. It is the process by which pollen is distributed by water. It is not common in flowering plants and occurs only in 30 genera which mainly monocotyledons.
Example: Vallisneria, Hydrilla

Note: Pollination is the method of reproduction in the flowering plants. It is defined as the transfer of the pollen grains from the anther when it is opened to stigma of carpel is known as the pollination.
Pollen grains produced by anemophilous in huge quantities are 5000000. Anemophilous and hydrophily flowers are small, colorless, odorless, and nectorless.
