In the previous segment of the chapter ‘Reproduction in Animals’, we learnt about the female reproductive system. In this segment, let us get acquainted with the Fertilisation Process.
What is Fertilisation?
- The process in which a male gamete fuses with a female gamete giving rise to a zygote is called Fertilisation.
Fertilisation Process
- When one sperm among all the others is able to penetrate the egg cell then the egg releases certain chemicals. These chemicals make sure that no other sperm will now penetrate the egg.
- The male nucleus from the sperm fuses with the female nucleus which is already present in the egg cell.
- The fusion stimulates a cascade of reactions which further gives rise to several successive cell divisions.
- The consecutive cell divisions then give rise to an embryo that will further develop into an organism.
