OSMOSIS



Osmosis is the movement of a liquid through a membrane when the movement is caused by a difference in the concentration of the liquid on either side of the membrane. When osmosis happens liquid will move from the side of the membrane with the higher concentration of the liquid to the side of the membrane with the lower concentration. An important example of osmosis is water moving in to and out of cells.
