WebDiffusion and osmosis represent the movement of substances (water in the case of osmosis) from an area of high to low concentration, down a concentration gradient. They are passive, and do not require energy. Active transport is the movement of substances from low to high concentration, against a concentration gradient. WebSome active transport mechanisms move small-molecular weight material, such as ions, through the membrane. In addition to moving small ions and molecules through the membrane, cells also need to remove and take in larger molecules and particles.
