Simulation of osmosis across the cell membrane using dialysis bags models to measure the direction and the rate of osmosis
Osmosis refers to the process by which the cells exchange their water content with their surroundings (Beckett, 1986). The process is passive just like diffusion only that osmosis involves water only. The water molecules move from a where their concentration is high to a where their concentration is low, through a membrane that is semi-permeable. The permeable membrane only allows water molecules are other small molecules to pass while preventing large and other charged molecules from passing. The pressure that is exerted by the molecules of water that are freely moving in a system is known as the water potential (Kent, 2000). ...
