Osmosis is the net diffusion of water from a weak solution to the more concentrated solution when the two are separated by means of a semi permeable membrane.
Diffusion is, therefore, the movement of molecules or ions of a solute or a solvent, be it a solid, liquid or gas from the region of its higher concentration to that of its lower concentration.
Active transport usually occurs across the protoplasmic membrane (i.e., plasma membrane, tonoplast, etc.). Active transport is not spontaneous and does not proceed towards an equilibrium. The devine force for active absorption is energy derived from metabolic processes.
