Osmosis and Diffusion
Diffusion: Movement of particles from high concentration to low concentration (down the gradient). No energy required.
Osmosis: Diffusion of water across a semipermeable membrane — from low solute concentration (high water concentration) to high solute concentration. Water moves toward where there is more dissolved material.
