Osmosis is defined as the movement of solvent from high solute to low solute concentration through semipermeable membrane. Semi-permeable membranes allows some things to pass through them but prevent other things.
Osmotic pressure is defined as the pressure applied to solution to stop movement of solvent molecules through semipermeable membrane.
Diffusion is defined as movement of particles from high to low concentration until the equilibrium is reached.
Simple diffusion do not need energy whereas facilitated diffusion require energy in the form of ATP.
Example of diffusion: by perfuming sprays into the air then aroma of perfume will be all around.
