Pollination:- Its transfer of pollen frm anther of one plant to stigma of otr[allogamy] or same[autogamy] plant.
Anther break down and release millions of pollens wic land on another flower's stigmatic surface leading to the process of pollination!
Fertilization:- Its union of male and female gamete leading to a zygote
Pollen tube germinate and passes through compatible stigma carrying 2 gamets
In tat 1 gamete carry male nucleus, otr gamete jus help in elongation of tube to reach ovary.
Tube penetrates ovary[Embryosac] and release male nucleus which fertilize egg cell thus leading to fertilization process.

Pollination is the transfer of pollen from a male part of a plant to a female part of a plant, enabling later fertilisation and the production of seeds, most often by an animal or by wind.Pollinating agents are animals such as insects, birds, and bats; water; wind; and even plants themselves, when self-pollination occurs within a closed flower. Pollination often occurs within a species. When pollination occurs between species it can produce hybrid offspring in nature and in plant breeding work.
Only after pollination, when pollen has landed on the stigma of a suitable flower of the same species, can a chain of events happen that ends in the making of seeds. A pollen grain on the stigma grows a tiny tube, all the way down the style to the ovary
