Detailed explanation-1: -The ‘cell membrane’ (also known as the plasma membrane or cytoplasmic membrane) is a biological membrane that separates the interior of all cells from the outside environment. The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells.
Detailed explanation-2: -Cell Membrane (Plasma Membrane) The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.
Detailed explanation-3: -Plasma membrane. The plasma membrane is the outer lining of the cell. It separates the cell from its environment and allows materials to enter and leave the cell. Ribosomes.
