In this video, you will learn all about Sexual Reproduction in Plants: Fertilisation
Let us recall that pollination involves both, the male and the female reproductive parts of a flower. When a pollen grain lands on the sticky stigma of the same kind of flower, it sends out a tiny thread-like tube, called the pollen tube, down the style of the pistil. The male gametes are then carried to the ovules in the ovary through this tube.
Once there, a male gamete enters an ovule and fuses with the female gamete or egg, to form a fertilised cell called a zygote. The fusion of the male and female gametes, to form a zygote, is called fertilisation.
After fertilisation, the zygote develops into an embryo, the ovule changes into a seed, and the ovary turns into a fruit. All other parts of the flower dry up and wither away. When provided with the favourable conditions, a seed grows into a new plant.
