The Cell and the Plasma Membrane

Front

Functions of the plasma membrane

Back

1. 1. Separates contents inside cell from outside environment.

2. 2. Controls movement of molecules in and out of the cell

3. 3. Allows the cell to be recognised as belonging to the body.

4. 4. Allows cells to signal to each other.

5. 5. Holds components of chemical reactions in place (e.g., enzymes).

6. 6. Allows molecules to bind to receptors in the membrane (e.g., hormones).
