Cell signalling.

- They communicate using messenger molecules. A cell releases a messenger molecule. This molecule travels to another cell. The messenger molecule is detected by the cell because it binds to a receptor on its cell membrane.

- A cell that responds to a particular messenger molecule is called a target cell.
