Solution and Explanation

Pollination is the transfer of pollen grains from the anther to the stigma of a flower. It occurs through abiotic and biotic agents.

Abiotic agents (Non-living agents):

  • Wind (Anemophily): Pollen grains are light, dry, and produced in large quantities.
    Examples: Maize, wheat.
  • Water (Hydrophily): Occurs in aquatic plants where pollen is transported through water currents.
    Examples: Vallisneria, Hydrilla.

Biotic agents (Living agents):

  • Insects (Entomophily): Brightly colored flowers with nectar attract insects like bees and butterflies.
    Examples: Sunflower, rose.
  • Birds (Ornithophily): Large, brightly colored flowers provide nectar to birds like hummingbirds.
    Examples: Bignonia, Coral tree.
  • Bats (Chiropterophily): Nocturnal flowers with strong fragrance attract bats.
    Examples: Bauhinia, Banana.
