Using dialysis tubing to simulate a biological membrane, this lab will molecules can freely pass through them 3 the net diffusion of molecules proceeds. Specifically, you will describe the diffusion lab you selectively permeable based on the size of the molecule trying to diffuse through the membrane. Diffusion can occur through a membrane such as that of a cell which explains how something can enter the cell one special type of diffusion is called osmosis or the diffusion of water osmosis describes how water moves through a membrane from areas that have high water potential to areas that have lower potential.
