Why is cell specialisation (differentiation) important for the development and growth of a healthy baby from a fertilised egg? !

Cell specialization is important in the development and growth of a healthy baby because cells differentiated to form different tissues, which organizes themselves to forms organs.

Explanation:

The development of an organism is divided into two processes, differentiation, and growth.  The body contains two types of cells undifferentiated cells can become any cells, while differentiated cells have a specific role. Differentiation is the process in which cells change from an undifferentiated cell and become specialized (differentiated cell). On the other hand, growth is the process by which already differentiated cells reproduce to increase the size of the tissue.
