Diffusion Experiment: Osmosis in Sucrose Solutions Abstract We used dialysis tubing to simulate a semi-permeable membrane. Since molecules diffuse from their higher concentration to their lower concentration‚ water will move across the membrane in response to this concentration. While conducting this lab we were able to observe passive transport through diffusion and osmosis. Introduction Osmosis is a specialized case of diffusion that involves the passive transport of water. When
