What is the name of the surface of the cell?

Every cell in the body is enclosed in a tiny membrane bubble. The plasma membrane not only defines the boundaries of the cell, but also allows the cell to interact with its environment in a controlled manner. Cells must be able to exclude, accept and excrete various substances, all in specific quantities. In addition, they must be able to communicate with other cells, identify themselves and share information. To fulfill these roles, the plasma membrane requires lipids, which make a semipermeable barrier between the cell and its environment.
