From fertilization till the eighth week of pregnancy, the developing human is called an embryo. First, it divides into two cells; then divide again to give four cells. This cell division is repeated many times until morula is produced after about three days. The cells in the morula continue to divide until it becomes a hollow ball of cells called the blastocyst at about five days after fertilization.
