OSMOSIS

Osmosis: diffusion of water molecules through a selectively permeable membrane from an area of higher water concentration to an area of lower water concentration.

INTRODUCTION: Osmosis is a type of diffusion, it essentially is the diffusion of water molecules through a selectively permeable membrane. As the diagram below illustrates if you put a selectively permeable membrane between concentrated and not so concentrated sugar water the water will diffuse through the membrane to even out the mixtures.

THE IMPORTANCE OF OSMOSIS: Every living thing on earth requires osmosis to survive. Water has to be able to travel in and out of cells and other membranes in order for a body to function.
