Question

Describe the pollination brought through the agency of insects and explain with suitable examples the adaptations of plants for this type of pollination.

Answer 1

Pollination by insects, called entomophily, involves the transfer of pollen by insects like bees and butterflies seeking nectar or pollen. Plants adapt by having brightly coloured, scented flowers with nectar to attract insects. Their pollen is sticky or spiny to adhere to insect bodies, while stigmas are also sticky to catch pollen. Flowers often have stamens and stigmas positioned to ensure pollen sticks to and is deposited by visiting insects. Examples include clover and butterfly-pollinated snapdragon.
