Why is the cell the basic unit of structure and function?

Cells are considered the basic units of life in part because they come in discrete and easily recognizable packages. That’s because all cells are surrounded by a structure called the cell membrane — which much like the walls of a house serves as a clear boundary between the cell’s internal and external environments.
