Verified step by step guidance1
Understand the different types of movement across a cell's plasma membrane: simple diffusion, osmosis, facilitated diffusion, and active transport.
Simple diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration without the use of energy.
Osmosis is a specific type of simple diffusion that involves the movement of water molecules across a semipermeable membrane from a region of low solute concentration to a region of high solute concentration, also without energy.
Facilitated diffusion involves the movement of molecules across the plasma membrane through protein channels or carriers, down their concentration gradient, and does not require energy.
Active transport is the movement of molecules against their concentration gradient, from an area of lower concentration to an area of higher concentration, and requires energy in the form of ATP.
