Question

What are advantages of the following in the flower to the plant concerned ? a) long & feathery stigma b) brightly coloured petals c) smooth & light pollen d) protruding & easily movable anther e) fragrant nectar

Answer 1

Long, feathery, smooth and light pollen promotes wind pollination. Hence, they are advantageous to wind pollinated flowers. 

2. Brightly coloured petals and fragrant nectar attract insects, birds etc. to pollinate the flower. Nectar is the reward that bees get in return of pollinating the flower. Hence, this helps in insect pollination.

3. Protruding and easily movable anther helps in pollination of flowers by wind.
