Osmosis is a spontaneous move and directed diffusion of the substance through the partially permeable membrane, which separates the substance form the pure solvent or from the substance with the less concentration. Osmosis is caused by the need of the system to the thermodynamic equilibrium and equalization of the concentration of the substance on the both sides of the membrane. Osmosis is characterized with the osmotic pressure which is equal to the excessive external pressure which should be put from the side of the substance in order to stop osmosis. Osmosis plays a very important role in the physiologic processes and is used in the study on polymers and biologic structures.

For the purpose of this report, the emphasis will be on passive transport.
