Exercise 1 Plant Cells and Osmosis In this exercise, you will use potatoes to explore the properties of a living membrane system. Potato strips will be placed in sucrose solutions of varying concentrations. Initial mass and mass after soaking in the solutions for 24 hours will be compared. You will determine whether water enters or leaves the potato cells, and you will classify each solution as hypotonic, hypertonic, or isotonic.
