The plasma membranes are selectively permeable as the proteins mosaic lets only some selected molecules to pass through it. The transport of these selected molecules occurs in two ways: Passive transport , in which the movement of molecules across the membranes occurs by diffusion along the concentration gradient. It includes osmosis, facilitated diffusion, and simple diffusion. In energy-requiring transport , the movement of molecules across the cell membranes, against the concentration gradient, is facilitated by the expense of energy by the cell. It includes exocytosis, endocytosis, and active transport.
