The plasma membrane has two major functions. It can first control the material exchange in and out of the cell through the three major transportation pathways. It can also facilitate the signalling between cells. Firstly, there are receptors on the plasma membrane, therefore, enzymes can bind to the receptor in order to trigger downstream activities. Transmitters can also be transported through the cell membrane. And there are plasmodesmata between cells for them to communicate.
