Describe how fertilisation takes place after a pollen is deposited on the stigma of a flower

Answer:

After pollen grains land on the stigma, a pollen tube grows from the pollen grain, through the style, and into the ovary. Sperm cells inside the pollen grain travel down the pollen tube and into the ovary which contains the ovules. Fertilization occurs when one of the sperm cells fuses with the egg inside of an ovule.

After pollen is deposited on the stigma, it must germinate and grow through the style to reach the ovule. The microspores, or the pollen, contain two cells: the pollen tube cell and the generative cell. ... The fertilized ovule forms the seed, whereas the tissues of the ovary become the fruit, usually enveloping the seed.
