Solution
Pollination is the reproductive mechanism in plants in which the pollen grains are moved from the male anther of the flower to the female stigma of the same or another flower of the same or another species.
Complete answer:
Sr.no | Agencies | Type of pollination |
---|---|---|
1. | Water | Hydrophily |
2. | Insect pollination | Entomophily |
3. | Bat | Chiropterophily |
4. | Bird pollination | Omithophily |
Hydrophily: The pollination is carried out with the aid of water and is known as a hydrophilic cross-pollination method. In aquatic plants, it is usually observed where pollen is produced in large amounts and with a specific weight that makes them float below the surface. The male flower floats on the surface of the water in Vallisneria until the female flowers come into contact.
Entomophily is a form of pollination in which pollen or spores are spread by insects. Several insects, in particular bees, Lepidoptera (butterflies and moths), wasps, flies, ants, and beetles, are known to be responsible for the (potential or effective) pollination of many plant species.
Chiropterophily (Chiropteran means bat) is a type of pollination that occurs with the help of bats. In these plants, the flowers are large enough to keep the bats against the flowers. Flowers are collecting nectar. In order to produce a considerable quantity of pollen seeds, the flowers have a large number of stamens. For e.g., Anthocephalus (Kadamb), Kigelia pinnata , Adansonia (Baobab tree), and Bauhinia.
Ornithophilic pollination is known as the method of bird pollination. Birds that feed on flower materials and fruits often cause pollen grains to spread to other nearby flowers. Flowers like this are considered to be Ornithophilous.
Note: Approximately 80 percent of all plant pollination is biotic, i.e., insects such as bees, wasps, and birds. The remaining 20 percent of abiotic pollinated plants are pollinated by wind,98 percent by wind, and 2 percent by water pollination.
