Can starch diffuse across dialysis tubing
WebAbstract Diffusion is the movement of particles from an area of high concentration to an area of low concentration. The diffusion of water molecules across a semipermeable membrane is osmosis. A semipermeable membrane only allows water and other small particles through to be diffused by osmosis. A cell membrane is similar to dialysis tubing.
