Question

What helps to bring pollengrain to the stigma

Answer 1

Explanation:

It is carried out by cross-pollination by agents like insects,wind and sometimes even water.

Firstly in few of the plants, the stigma is quite sticky and is wide open in the case of wind pollination. ...

Thereby, the pollen grains get transferred to stigma in cross and self pollination.

Answer 2

Answer:

when pollen grain goes to the stigma, a pollen tube begins to grow and the pollen grain falls and goes inside the ovary and then fertilization takes place

the process of fertilization inside the ovary is very large so I'm not gonna explain that. Just remember this that a zygote is formed after the merging of the male parent cell(pollen grain) and female parent cell(ovules) and then an embryo is formed.
