By one week after conception, the multiplying cells have divided into outer cells enclosing a mass of inner cells. The inner cells will become the embryo.
Explanation:
By week one, the outer cells will give the trophoblast, which will later become the placenta, while the inner cells will form the embryoblast, which will become the embryo.
