What is the purpose of cell differentiation?
The purpose of cell differentiation is to provide organisms with the many different types of specialized cells needed to perform specific functions. Organisms start from a single cell that contains all the required genetic information, or instructions, which reproduces into many stem cells with the potential to become any type of specialized cell. First, it is decided which genetic information will be expressed, or carried out, thereby indicating the type of cell that is to be formed. Then, through cell differentiation, those instructions are carried out and specialized cells are formed.
