What's the difference between cell division and cell differentiation?

Cell differentiation allows a cell to specialize to achieve a specific function Multicellular organisms (eg: humans) have different types of cells which have different functions. For example: a muscle cell needs to contract, while a sperm cell needs to swim to the egg. Cell differentiation is the process by which cells specialize to achieve their required functions. In order for a cell to differentiate, it will express specific genes. Once a cell has differentiated, it loses its ability to undergo mitosis (see below). Cell division involves splitting of a cell  Mitosis is a form of cell division : this is the process by which cells split to form new cells. During the life of any living organism, there is always a need to form new cells, eg: when you scrape your skin, some of the cells that have died are replaced by mitosis. Importantly, mitosis produces cells that are identical to each other (clones).
