Which of the lahelled parts​

Answer 1

Explanation:

Anemophily

It is a form of pollination when pollen grains are distributed by wind. Also, called the anemophilous flower.

Anemophilous pollen grains are light and non-sticky. So, that it can be transferred by air currents. Wind-pollinated flowers are inconspicuous and they not showy and also devoid of nectar etc. as seen in grass

Hydrophily

It is a form of pollination when the pollination takes place through the agency of water.

It is of two types :

Hydrophily: Plants which are pollinated inside the water. e.g. Zoster, Ceratophyllum

Epihydrophilly: Plants which are pollinated outside the water or on the surface of the water. e.g. Vallisneria

Entomophily 

It is a type of pollination, which takes py insect. Insect-pollinated flowers are made attractive in different ways and the pollens are sticky with a rough surface. So, that they may easily stick to insect limbs. e.g. Rose

Ornithophily 

It is the form of pollination when the pollination takes place by birds. e.g. Begonia, Bottlebrush, Butea
