Definition of Embryogenesis

Embryogenesis is a process in which an embryo is formed and developed. The characteristic of embryogenesis is that there are multiple division of cells and the cells of the embryo are differentiated too. These processes of division and differentiation take place during the early developmental phases. 


The development of a human body starts from a zygote which is a single-celled entity formed as a result of the fusion of a sperm cell with an ovum during the process of fertilization. For three months, it is termed as an embryo but after 3rd month, it is called a fetus. In a fetus, all the organs are developed but their growth has yet to happen.
