Hey!
Pollination is the transfer of pollen (which contains the male sex cells) from an anther (part of the male reproductive organ) to a stigma (part of the female reproductive organ).
→ This process precedes fertilisation.
→ Pollination may occur within the same flower (self-pollination), or between flowers on separate plans of the same species (cross-pollination).
→ In most plants, pollination is carried out either by insects (entomophilous pollination) or by the wind (anemophilous pollination).
→ Insect-pollinated flowers are typically brightly coloured, scented, and produce nectar, on which insects feed whereas wind-pollinated flowers are generally small and unscented.
{You will less commonly see birds, bats or water as the agents of pollination.}
Hope this helps! :)

__________________________________________________________________________________________________________________
POLLINATION
The process of transferring of pollen grains from anther to stigma for fertilisation is called pollination.
Pollination is of two types:
1. Self Pollination
2. Cross Pollination
SELF POLLINATION
When pollen from the anther of a flower is transferred to the stigma of the same flower or to the stigma of another flower in the same plant, it is called self pollination.
Self pollination does not requires any outside agents for their purpose.
CROSS POLLINATION
When pollen from the anther of a flower is transferred to a stigma of a flower in another plant, it is known as cross pollination.
Cross pollination requires outside agents like insects, wind etc.
