Dialysis tubing vs cell membrane

WebA special type of passive transport is the movement of water across a membrane, or osmosis. By definition, osmosis is the diffusion of water through a selectively permeable membrane from an area of high water potential (low solute concentration) to and area of low water potential (high solute concentration). Therefore, for osmosis to occur, the ... WebMay 8, 2024 · Osmosis & Diffusion Lab – Dialysis Tubing Introduction. The movement of molecules through a cell membrane is termed osmosis or diffusion. Such movement is principally possible because nutritive molecules are smaller than membrane micro pores. If the molecules are too large, no molecular transfer, or diffusion occurs.
