The plasma membrane is selectively permeable, which means it allows only certain molecules to pass through it. This characteristic is responsible for maintaining the difference between intracellular and extracellular fluids by regulating the exchange of molecules between the two regions. It allows certain molecules to enter or exit the cell while blocking others, thereby preventing the mixing of intracellular and extracellular fluids.
