Answer 1

Pollination:

1. The transfer of the pollen grains from anther of a stamen(male part) to the stigma of a pistil (female part) is called pollination.
2. Pollination is of 2 types- Self pollination, cross pollination.

Types of pollination on the basis of its agent:

1. Wind Pollination:
   • Agent which facilitates the pollination is wind.
   • Dull flowers with no scent and nectar.
   • Small and light pollen grains are present.
   • Sticky and feathery stigma is present.
   • Examples: Wheat, rice, corn
2. Water Pollination:
   • Pollination in aquatic plants is done by water.
   • Lightweight pollen grains are produced in aquatic plants and are released in large numbers.
   • Pollen grains travel from one flower to another with water currents.
   • Feathery stigma is present.
   • Examples: Vallisneria and Hydrilla
3. Insect Pollination:
   • Agents which facilitate the pollination in between flowers are insects.
   • Bright colored flowers with nectar and scent are present.
   • Stick and heavy pollen are produced in such flowers.
   • Bougainvillea is an example of insect pollinated flower.
