(Weak to concentrated solution) through a semi permeable membrane until concentrations become uniform (equal on both sides of the membrane). But osmosis also affects other factor such as plant and animal cells. This knowledge has come from a textbook. In animal cells have red blood cells, which contain solutions such as salts and other substances. But when these cells are placed in water they expand.

But when the cells are bathed in a concentred solution, the water...
