Embryogenesis
Embryogenesis (compound of the Greek: εμβρυο-γένεσις "embryo-genesis") is the process by which the embryo is formed and develops. It starts with the fertilization of the ovum (or egg) which, after fertilization, is referred to as a zygote. The zygote undergoes rapid mitotic divisions with no significant growth (a process known as cleavage) and cellular differentiation, leading to development of an embryo. It occurs in both animal and plant development, this article addresses the common features among different animals.
