Question

explain the types of pollination

Answer 1

Pollination is when pollen grains from an anther, the male portion of a flower, are transferred to a female part in the flower, known as the stigma.
There are two types of pollination, called self-pollination and cross-pollination.

Self-pollination is the more basic type of pollination because it only involves one flower. This type of pollination occurs when pollen grains from the anther fall directly onto the stigma of the same flower. Although this type of pollination is simple and quick, it does result in a reduction in genetic diversity because the sperm and egg cells of the same flower share genetic information.

Cross-pollination is a more complex type of pollination that involves the transfer of pollen from the anther of one flower to the stigma of a different flower. This type of pollination results in an increase in genetic diversity because the different flowers are sharing and mixing their genetic information to create unique offspring.

Answer 2

self pollination involved single parent.In this process only one individual reproduce.
and cross pollinatin involved two parents means the one plant have male gamete and other plant have female gamete and they both fuse together
