Explain the process of osmosis
Osmosis is the process whereby water molecules move from a region of low solute concentration across a cell membrane to a region of high solute concentration. A solute is a substance (such as a protein or electrolyte) that is dissolved in a fluid. While water molecules can move freely across most cell membranes, solutes generally cannot. A high concentration of solutes generates a force that attracts water, diluting the higher concentration of solutes. Thus, the driving force behind osmosis is the difference in intracellular and extracellular fluids' solute concentrations. The movement of water ceases when the concentration of solutes is the same on both sides of the cell membrane.
