Transport and diffusion

movement of particles against a concentration gradient using ATP energy across a semi-permeable membrane

movement of particles down a concentration gradient across a semi-permeable membrane

passive movement of particles across a semi-permeable membrane using protein pumps

the movement of particles from an area of high concentration to an area of low concentration through a semi-permeable membrane

the movement of water molecules from an area of high concentration to an area of low concentration through a semi-permeable membrane

osmosis, facillitated diffusion, diffusion
