Answer 1

Pollination:

2. It occurs in sexually reproducing plants.

It can be carried out in two ways:

• The process that involes the transfer of pollen from an anther of one flower to the stigma of another flower is called cross-pollination.
• Cross-pollination can occur by various biotic polinators like bees, bats, etc, abiotic pollinators like wind, water, air and can also be done by artificial ways.

2. Self-pollination:

• The process that involves the transfer of pollen from an anther of a flower to the stigma of the same flower is called self-pollination.
• In self-pollinating plants, pollinators are not required.
