WebFluid Mosaic Model of the Membrane The plasma membrane is more than just a sack to hold the contents of the cell. It plays an important role in cellular function and the maintenance of homeostasis. One obvious function is to regulate what enters and leaves the cell. This process is highly coordinated and very specific. WebThe plasma membrane controls the exchange of materials between the cell and its surroundings. Selective permeability: some substances cross more easily than others. …
