Embryo vs Fetus. Embryo and fetus are different stages in the human reproduction process. The human life starts when the sperm and ovum (egg) get together to form the fertilized ovum. Fertilized ovum starts to divide and produce more cells. When it starts to divide in to two cells, 8 weeks from fertilization, the period is called embryo period. The dividing cells collectively forms the embryo.
They are fertilized by male sperm either inside the female body (as in birds), or outside (as in many fish). After fertilization, an embryo develops, nourished by nutrients contained in the egg. It then hatches from the egg, outside the mother's body. See egg for a discussion of eggs of oviparous animals.he ovum is one of the largest cells in the human body, typically visible to the naked eye without the aid of a microscope or other magnification device. The human ovum measures approximately 0.12 mm in diameter.
