in biological aspect, generally diffusion is a process of the spread of a solute in a solvent from higher concentration to lower concertration. . example, a piece of salt when we place into water after a few hour the water will be tasted salty. it is because the salt was diffused in water. Osmosis is always concern about solvent (water), i.e Osmosis is a process concern about the move of the water from higher potential to lower water potential via the semipermiable membrane. active transport is move of a sustance from lower concentration to higher concentration and energy is required in this process.

diffusion is the movement of particles from areas of greater concentration to areas of lesser concentration.
osmosis is the diffusion of water through a semi-permeable membrane
Active transport requires the use of energy, usually moving particles from areas of lesser concentration to areas of greater concentration
