Feathery stigma occurs in.
A)Pea
B)Wheat
C)Datura
D)Caesalpinia

Answer 1

Hint: The term anemophily refers to the manner in which pollination takes place through the wind. These are the wind-pollinated vegetation also recognised as anemophilous plants. barley, corn, and some grasses that use wind for pollination.

Complete answer:
For wind to raise the pollen grains from a flower the pollen grains have to be lightweight and non-sticky so that it can be easily carried away. These plant lives have to produce a giant variety of pollen grains because the likelihood of pollen accomplishing the right plant is low. For pollination to show up completely, the pollen has to attain the desirable stigma.

The adaptations are such that the pollen have to be trapped via the stigma to prefer pollination. For this, the stigma is designed large and feathery/brushy. This feathery character helps it to entice the pollen grains. Further, the stigma is prolonged and protruded out to capture the grains easily. The flowers, on the different hand, are small and inconspicuous. They do not now require attracting insects. When the wind passes by, it contains the pollen grains along with it. The wind contains the pollen away to reach the stigma of another plant.

Here the stigma being feathery catches the pollen for that reason easing the pollination. Sessile stigma is the presentation in which the fashion is very brief and is without delay in level with the ovary. Colored plants are usually current to attract the insects toward the plant so that they can accumulate the pollen from the flower and credit on the stigma of some other flower.

Hence, the correct answer is option (B)

Note: The anemophilous plant life does not produce flowers with scent or nectar. These elements are existing in insect-pollinated plants. The lightweight of the pollen grains makes it favourable for the wind to raise it.
The non-sticky nature helps the wind to without problems lift the pollen from the stamen.
