Fertilization is the process by which a new individual of the same kind is developed (or born). It differs from pollination, where the pollen is transferred from a male part (anther) to a female part (stigma).

Fertilization takes place in a flower when ripe pollen (from the same type of flower, typically carried by wind or insects) from the anther is transferred to the stigma, threadlike tubes that are generated from the pollen grain. This pollen tube enters the ovule (of the ovary) and releases sperm cells, which fuse with the eggs inside the ovule, leading to fertilization. Once the ovule receives the entire content of the pollen tube, it fertilizes and develops into a seed (encasing the embryo and endosperm in a seed coat).

Note that in flowering plants double fertilization takes place.

Answer 2

First pollination occurs. In this process, the pollen grains from the anther fall on the stigma of the flower. The flower produces some secretions which help in the growth of the pollen tube. Sometimes, the pollen tube fails to generate due to several reasons. This pollen tube reaches the ovary. This is how fertilization occurs.
