Question

Anemophilous flowers have

• A. Sessile stigma
• B. Small, smooth stigma
• C. Coloured and scented flowers
• D. Large feathery stigma

Answer 1

The correct option is D Large feathery stigma

Insect-pollinated flowers are large, conspicuous, bright coloured and have a pleasant smell. They have nectarines on receptacles or on spurs at the base of flower whorls and produce nectar to attract insects. Wind pollination does not require scented colourful flowers which makes option C incorrect. Wind-pollinated flowers have large, conspicuous, broad, well exposed and feathery stigma to catch windblown pollen. This makes option D correct. Sessile stigma has reduced style and stigma is directly seated on the ovary. Presence of sessile stigma will not expose it to wind to catch pollen. Option A is incorrect. A small and smooth stigma has less exposure to wind and less exposed surface area to catch pollen as well as its smooth nature does not grab the wind-blown pollen. Option B is incorrect.

So, the correct option is 'Large feathery stigma'.
