Describe the reaction of osmosis.

Osmosis is the spontaneous net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides. It may also be used to describe a physical process in which any solvent moves across a selectively permeable membrane (permeable to the solvent, but not the solute) separating two solutions of different concentrations. When a cell is submerged in water, the water molecules pass through the cell membrane from an area of low solute concentration to high solute concentration. If the cell is submerged in water, the water moves into the sucrose solution because sucrose solution has higher solution than that of water.
