WebIn these experiments, we investigated the passage of materials through a semipermeable membrane by passive transport. This tubing allows larger molecules to pass through, but slowly. The movement of molecules from areas of higher concentration to areas of lower concentration is called diffusion. Diffusion is the process by which molecules spread from areas of high concentration to areas of low concentration. This movement, down the concentration gradient, continues until molecules are evenly distributed. Osmosis is a special type of diffusion: the diffusion of water through a semipermeable membrane.
