7. Plasmolysis in Elodea and in onion cells. 1.Set up slides of Elodea cells and onion cells, with tap water medium. 2.Find cells under the microscope. Draw and label what you see. Include magnification. You might need to try different stains. 3.Draw salt solution through the slides. Observe and draw the effects. 4.Explain the effects of changing the salt concentration on the cells.
