Answer:
Fertilised egg i.e., zygote divides and redivides and forms a ball of cells. This is a kind of embryo and it reaches the uterus and gets attached to the wall of the uterus. … Thus the zygote forms an embryo, it forms a baby and it forms an adult.
As a fertilized human egg divides, it first becomes a solid ball of cells, the morula. The cells of the outer layer of the blastocyst eventually from part of the placenta. Inside the ball is a small clump of cells, the inner cell mass, that will form all the tissues in the body.
