Question

What are the advantages of the following in the flower to the plant concerned?
(a) Long and feathery stigma
(b) Brightly coloured petals
(c) Smooth and light pollen
(d) Protruding and easily movable anthers
(e) Fragrant nectar

Answer 1

a) Long and feathery stigma allows catching of dispersed pollen grains in the wind and increases the adhesiveness of the attachment.

b) Brightly coloured pistils are responsible for attracting insects and birds towards the flower and allow the dispersal of pollen by the mode of these insects and animals.

c) Smooth and light pollen are easily carried by wind and are characteristic of wind-pollinated plants.

d) Protruding and easily movable anthers swing hard on the contact of wind and help in pollen dispersal by wind due to their fragility.

e) Fragrant nectar draws in nectar sucking insects and allows pollination by Entomophily.
