Osmosis is the process in which water particles move from an area of high water concentration to an area of low water concentration through a semi-permeable membrane until the concentrations are equal.

Osmosis has the same basic theory as diffusion. Particles are moving from an area where they are in great concentration to an area where they are in low concentration until the concentrations are the same. Osmosis is this movement of water particles and the particles must move through a semi or partially permeable membrane (a membrane that lets some things through but not others). An example of this type of membrane is a cell wall, like in a potato. Osmosis occurs when two things occur. One is if the cell has no water in it or has less water then the solution it is placed in. If this is the case then water will go from the solution, for it is the area of high water concentration, into the cell, for this is the area of low water concentration. If the cell has no water within it the cell is flaccid. As the water passes through the cell membrane, the cell fills with water and becomes turgid. Once the cell becomes turgid, no more water can enter the
