"WebOsmosis is the diffusion of water. And usually you're talking about the diffusion of water as a solvent and usually it's in the context of a semi-permeable membrane, where the actual solute cannot travel through the membrane. Anyway, hopefully you've found that useful and not completely confusing. Up next: video. " - How does sucrose move across a membrane
