Semipermeable membranes are thin biological sheets of material that allow certain molecules to pass through them more easily than others. The molecules tend to move from areas of high concentration to areas of low concentration - a process called diffusion. An example of a semipermeable membrane is a cell membrane.

What is a semipermeable membrane called?
