ANSWER
Pollination: Is defined as the deposition of pollen grains on the stigma of a flower from anthers belonging to the same flower, same plant or a different plant.
Pollination is of two types
Self pollination - Stigma receiving pollen grains from the same flower
Cross pollination - Stigma receiving pollen grains from a flower on the same plant or a different plant
Wind and insects are two agents of pollination, called as Anemoplily and Entomophily respectively
Example of wind pollination - Grasses, Gymnosperms etc
Example of insect pollination - Rose, Euphorbia sps etc
Pollination and fertilization - Suitable pollination leads to compatible pollen grains being deposited on the stigma, leading to pollen tube development and fertilization.
Mammals, Reptiles, Birds, and Insects. Beetles, Bees, Moths, and birds are examples of biotic pollinating agents
