Detailed explanation-1: -Pollination is simply the transfer of pollen grains from an anther to a stigma. Fertilization occurs much later when the pollen grains germinate on the stigma and send down a pollen tube which releases the sex cells to fertilize the ovules.
Detailed explanation-2: -Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma. The goal of every living organism, including plants, is to create offspring for the next generation. One of the ways that plants can produce offspring is by making seeds.
Detailed explanation-3: -After pollen lands on the stigma, it initiates pollen tube formation. Pollen tubes are channels which grow down the length of the style to the ovules. After a pollen grain travels down a pollen tube it intercepts an ovule, fertilizes the female germ cells and initiates seed development.
