The specialisation of cells depends almost always on the exaggeration of properties common to cells. Cells lining the intestine for example have extended cell walls that increase the amount of surface area that is available to absorb food.
The structures and functions within a cell often are compared to similar activities in a typical city. There is no such thing as a typical cell but most cells have chemical and structural features in common. As an individual unit, the cell is capable of metabolizing its own nutrients , synthesizing many types of molecules, providing its own energy, and replicating itself in order to produce succeeding generations.
Other cells acquire specialized functions as they mature. What Exactly Is a Black Hole? Many cells carry out specialised functions; this is what makes them different. You may find it helpful to search within the site to see how similar or related subjects are covered.
