4. It is responsible to regulate the transportation of materials and the movement of substances in and out of the cell.

The function of plasma membrane:

1. The main function of the plasma membrane is that it acts as a physical barrier between the external environment and the inner cell organelles.
2. The plasma membrane is a selectively permeable membrane, which permits the movement of only certain molecules both in and out of the cell.
3. The plasma membranes also play an important role in both the endocytosis and exocytosis processes.
4. The plasma membrane also functions by facilitating communication and signaling between the cells.
