Fertilisation results in the formation of zygote which begins to develop into an embryo. The zygote 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 termed an embryo. The embryo gets embedded in the wall of the uterus for further development.

Amnion, in reptiles, birds, and mammals, a membrane forming a fluid-filled cavity i.e. amniotic sac that encloses the embryo. The amnion of mammalian embryo is derived from ectoderm on the inner side and covered with mesoderm (both are germ layers), it acts as a protective sac along with three other extraembryonic membranes: the chorion, the yolk sac, and the allantois. The amnion contains a thin, transparent fluid in which the embryo is suspended. It provides a cushion against mechanical injury providing a protective environment for the developing embryo.

The zygote is a fertilized egg that results from the union of a female gamete (egg, or ovum) with a male gamete (sperm). This process is known as fertilization. A zygote is further developed into an embryo. A zygote is a haploid cell. The zygote begins as a single cell but divides rapidly in the days following fertilization.
