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.
Embryonic development and parental care. Once the eggs are fertilized, development begins, and the egg becomes an embryo as it divides into successively smaller cells. The time delay between fertilization and egg deposition (that is, egg laying) is poorly documented for the majority of reptile species.
