The main need for pollination is the exchange of genetic material. Some plants use sexual reporductaion (requires pollen) others use asexual (clone) some use both.
Exchanging genetic material allows for adaptation, mutation and in the end survival. Without the exchange in gentic information and recombination of genes all the plants of the species would be excatly the same and could be wiped out by one disease.

Some plants require pollination to take place before fertilization can occur. While in other plants, vegetative propagative methods are used.

Pollination in plants is the same as sex in animals. Some plants require it to reproduce.

Because that is how plants reproduce.
The pollen is made and transferred by the wind, then the pollen sticks to the stigma part of a flower and fertilizes the plants ovum.

Some don`t need it, for they reproduce vegetatively, but it`s necessary to make seeds.
