The cell membrane is the structure that separates a cell and its environment. The cell membrane is an important part of the cell that provides an essential function to the cell protecting the cell and determining what is passed in and out of the cell.
The boundary between a living cell and its environment is the cell membrane, also known as the plasma membrane. It is composed of a phospholipid bilayer and proteins, which help in regulating what enters and exits the cell. This structure provides protection and facilitates communication with the environment.
