The cell membrane is semi-permeable. It allows some substances to pass in and out and others not. The proteins in the membrane are responsible for this function of control.

The cell membrane regulates the movement of substances in and out of the cell.How does it do this? The phospholipid bilayer is impermeable to most substances, allowing across only small, uncharged molecules such as those of oxygen, carbon dioxide, and water. The only way for other substances to cross the membrane is via transport proteins (channel and carrier proteins). These are selective, and therefore control what enters and what leaves the cell.

The semipermeable cell membrane which has two layers of phospholipids controls movement into and out of the cell membrane.
