Cells are the basic structural and functional unit of life and possess genes. These genes evolve to carry out new biological functions in the body.  
Cells undergo division and growth whether it be unicellular organisms or multi cellular organisms.  
All cells possess the property of compartmentalization and metabolism henceforth taking up nutritive material from the environment. 
These nutrients are further transformed into the cell compartments and the waste produced as a result is expelled out thus forming on open system.
