Virtual Lab: Diffusion and Osmosis in Elodea CellsQuestions and Predictions: Record response in your notebook.1. What is the difference between a hypertonic solution and a hypotonic solution?2. What will happen to plant cells that are placed in a hypertonic solution?ProcedurePlace one of the leaves on a slide and observe the cells under a microscope. (see images)

Observe what happened to the elodea. Be able to identify the chloroplasts and an empty space in the middle of the cells which is the vacuole.Soak the other leaf in a salt water solution and observe the cells under the microscope. Compare the cells to the first slide. (see images)

ObservationsSketch your slides, showing how the cells appeared in each solution. (see images)

Analysis: Describe in your own words what happened to the elodea cells.
