Diffusion through a selectively-permeable membrane: practical
In this lesson: I can explain observations of diffusion through a selectively-permeable membrane. Particles of some substances are small enough to diffuse through holes in a selectively-permeable membrane. Particles of these substances move through the selectively-permeable membrane in both directions.
