To clarify, all cells have a plasma membrane. The function of the cell membrane is to protect the cell and control the transport from the inside to the outside of the cell. It contains transport signaling systems such as protein channels through which substances such as salts pass.
Plasma membrane functions to hold the contents of a cell together and separates them from the external environment. Plasma membrane also selectively controls the movement of s â¦ ubstances going in or out of the cytoplasm, both actively and passively.
