Detailed explanation-1: -The plasma membrane is called as selectively permeable membrane because it regulates the movement of substances in and out of the cell.
Detailed explanation-2: -The Cellular Membrane The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells.
Detailed explanation-3: -The answer is proteins. Proteins dot the surface of the bilayer, floating like rafts. Some of these proteins have channels, or doors between the cell and the environment. The channels let larger things that are hydrophilic and normally couldn’t pass through the membrane into the cell.
