Question

Anemophilous plants have
A) Sticky stigmas
B) Feathery stigmas
C) Prominent nectaries
D) Colourful flowers

Answer 1

Hint: Anemophily is defined as the process of wind pollination wherein the wind distributes the pollen grains. Almost all representatives of the gymnosperm category are anemophilous.

Complete Answer:
The pollen grains produced by these plants are light and non-sticky which facilitates their transportation by wind.

Option A: Sticky helps in the exudation of complex substances that facilitates easy trapping of the pollen to prepare them for the process of fertilization. Anemophilous plants produce non-sticky stigmas. Hence, this is an incorrect option for the given question.
Option B: Anemophilous plants are known to produce large feathery stigmas which facilitates their easy dispersal by wind currents. Thus, this is the correct option for the given question.
Option C: Nectaries are defined as the nectar producing structures present within the flowers. These are present in the insect pollinated plants as the nectaries result in the production of the nectar which helps in attracting the insects to facilitate the process of pollination. Thus, this is an incorrect option for the given question.
Option D: Anemophilous flowers are inconspicuous as they lack bright colours. Thus, this is an incorrect option for the given question.

Thus, the correct answer for the given question is Option B i.e. feathery stigmas.

Note: Anemophily is considered to be an adaptation which assists in the separation of male reproductive organs from the female within a single anemophily plant thereby reducing the probable effects of inbreeding.
