Differentiated cells are important in a multicellular organism because they are able to perform a specialised function in the body. ... Multicellular organisms must therefore retain some unspecialised cells that can replenish cells when needed. These unspecialised cells are called stem cells.

Why can stem cells differentiate?

Embryonic stem cells (ESCs) are pluripotent cells that differentiate as a result of signaling mechanisms. ... The daughter cells divides and after each division it becomes more specialized. When it reaches a mature cell type downstream (for example, becomes a red blood cell) it will no longer divide.

Why do cells differentiate?

Cell differentiation creates all of the different structures in your body, like muscles, bones and organs. Cell differentiation also produces the vast number of organisms on Earth and allows for many different cell structures to exist and function both properly and efficiently.
