Question
What is pollination? Name the different agencies of pollination.
Solution
Pollination is the process by which pollen is transferred from the anther (male part) to the stigma (female part) of a plant, thereby enabling fertilization and sexual reproduction. This process is crucial in the reproduction of seed plants.
The different agencies of pollination are:
-
Wind (Anemophily): Some plants depend on the wind to transport their pollen from one flower to another. These plants typically produce light, dry pollen grains that can be carried by the wind. Examples include grasses, conifers, and many deciduous trees.
-
Water (Hydrophily): Very few plants use water as a means of pollination. In these plants, the pollen floats on the surface of water and reaches the stigma of the flower. Examples include some species of waterweeds and pondweeds.
-
Animals (Zoophily): Many plants depend on animals, particularly insects, to transport their pollen. These plants often have brightly colored, fragrant flowers to attract the animals. Examples include many species of flowering plants, such as orchids and lilies.
-
Birds (Ornithophily): Some plants depend on birds for pollination. These plants often have bright red or orange flowers to attract birds. Examples include hummingbird-pollinated plants like the trumpet vine and the bee balm.
-
Bats (Chiropterophily): Some plants depend on bats for pollination. These plants often have large, nocturnal flowers to attract bats. Examples include the saguaro cactus and the agave plant.
-
Humans (Anthropophily): Some plants depend on humans for pollination, especially those that are cultivated. This is often done by hand in a process known as hand pollination. Examples include many species of fruit trees and vegetables.

Pollinating agentsThe pollen-pistil interaction begins with pollination, followed by pollen adhesion to the stigma.After it adheres, it imbibes water and gets hydrated which initiates pollen tube germination.There are different agents of pollination like wind, insects, birds and water.Anemophilous flowers are pollinated by the agency of wind. These flowers are small andinconspicuous.. The pollen grains are very light, non-sticky and sometimes winged.Entomophilic flowers are pollinated by insects. These flowers are often attractive to look at withbright petals and are fragrant to attract the insect visitors to them. They often have broadstigmas or anthers to allow the insect to perch on it. Many of the insect-pollinated flowers alsosecrete nectar which attracts bees, butterflies or other similar insects to the flowers. The pollengrain surface of such flowers produce mucilaginous secretion.Hydrophilic flowers are pollinated by water. It is commonly found in algae, bryophytes,pteridophytes and some angiosperms.
