Diffusion is the movement of particles (atoms, ions or molecules) from a region in which they are in higher concentration to regions of lower concentration. A good example of diffusion is food colouring.If you place a drop of red food colouring in a beaker of water eventually the entire beaker of water will have a red tint. The food colouring moved through the water until it was equally distributed throughout the beaker.ere, the concentration is the same on both side of the membrane. The water moves through the membrane from both sides at equal rates. Osmosis and Animal Cells. The movement of liquids in and out cells is dependant on the concentration of the solution surrounding it.
