Cells specialize to carry out different jobs
... You started out as an unspecialized cell – a single cell, a fertilized egg. Really soon after an egg is fertilized by a sperm cell, it begins to divide. The single cell divides by mitosis until it forms a ball of cells called an embryo. At some early point in the life of this embryo, the cells begin ...
