Background: Plasmolysis. We will expose the chicken egg to a hypertonic environment to make it shrink, and a  Water moves through membranes by diffusion; this process is called osmosis. Review the Elodea activity if necessary. Lab 3. The osmosis lab has a section in which students are asked to calculate the ratios of solute to water at equilibrium and see that it is the same in both compartments. It actually allows students to explore the rate of water movement and quantify pressure changes occurring in the system. Osmosis factors heavily in each of these processes and is an important force for keeping every single cell in your body healthy. 5 Introduction: The first part of this three part lab was an investigation that examined the relationship between rate of diffusion and the surface area to volume ratio. Osmosis is the diffusion of water through a selectively permeable membrane (a membrane that allows for diffusion of certain solutes and water) from a region of higher water potential to a region of lower water potential.
