....,.................

Answer 2

Answer:

The pollen grain of the anther of the same or a different flower touches the stigma of the flower by one of the various means of pollination.

The pollen reacts with the sticky substance and various chemicals and releases a tube into the style of the flower, called a pollen tube.This tube helps the gametes to travel from the pollen to the ovules. It goes on the ovary and fertilises the ovule.

After fertilisation of male gamete with the female gamete , the ovules change to seeds and the ovary develops into a fruit. As this goes on, the petals and sepals of the flower fall off. And it develops into a fully grown fruit.
