To keep the cell compartments, such as the nucleus, mitochondria, and cytoplasm's pH, ions from the outside environment. Also, play an important role in cell-to-cell communication and transmits cellular signals.

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.
