Question

Differentiate between anemophily and entomophily.

Answer 1

Hint: Pollination is the transfer of pollen grains from the anther of one flower to the stigma of another or the same flower. Anemophily are those flowers in which pollination is carried out by wind. Entomophily are those flowers in which pollination is carried out by insects.

Complete answer:
Anemophily flowers and Entomophily flowers are differentiated on the basis of the method of pollination carried out in these flowers. There are many other differences also as follows:

 ANEMOPHILY-
1. These are wind pollinated flowers.
2. These flowers usually have a small size.
3. These are not brightly coloured flowers.
4. These flowers do not have any strong odour.
5. These flowers do not produce any kind of nectar.
6. These flowers produce pollen grains in large amounts.
7. Pollen grains of such flowers are light in weight and are smooth.
8. Stigma is branched or hairy.
9. Examples of such flowers are maize, jowar, monocot grass etc.

ENTOMOPHILY
 1. These flowers are pollinated by insects
 2. Size of flowers is usually large or flowers are present in large groups.
 3. Flowers are brightly coloured to attract pollinators.
 4. These flowers have odour.
 5. These flowers produce nectar.
 6. Pollen grains are less in number
 7. Pollen grains are heavy and sticky
 8. Stigma is usually sticky.
 9. Examples are jasmine, rose etc.

These are basic differences between anemophily and entomophily flowers.

Note: Process of pollination is mainly divided as self pollination or cross pollination. Self pollination is when the process of pollination takes in the same flower or other flower on the same plant. Autogamy is the term used for pollination on the same flower and Geitonogamy is a type of self pollination where pollination is carried out on other flowers of the same plant.
Cross pollination is agent dependent in this pollination occurs between two flowers of different plants. These are categorized as Hydrophilus- pollinated by water means. Zoophilous- pollinated by animals or human beings. Anemophilous- pollinated by wind. Entomophily- pollinated by insects. Ornithophilous- pollinated by birds.
