Question

Enumerate various adaptations of wind pollinated and insect pollinated flowers.

Answer 1

Adaptations of wind pollinated flowers are as follows:

• Both the stigmas and anthers are exserted.
• Pollen grains are dry, very small sized, non-sticky and unwettable, so that they can be carried by wind to long distances.
• Stigmas is hairy, feathery (grasses) or branched to catch the wind borne pollens.

Pollination by insects is called entomophily, adaptations for insect pollinated flowers are as follows:

• Insect pollinated flowers produce nectar, which attracts the pollinators for feeding.
• Some flowers produce edible pollen grains.
• Flowers are fragrant and emit scent and odour.
• Flowers are bright colored.
