Question

Discuss how a zygote develops into an individual in humans.

Answer 1

After the process of fertilisation, the zygote travels down in the oviduct and divides repeatedly to give rise to a ball of cells. The cells then begin to form groups that develop into different tissues and organs of the body. This developing structure is called embryo. The embryo gets embedded in the wall of uterus for further development. The stage of embryo in which our body parts can be distinguished easily is known as a foetus. The embryo/foetus grows in the mother's uterus for about nine month. After nine months, the mother is ready to give birth to a fully developed foetus.
