Diffusion and osmosis are not just theoretical concepts that can be shown in sketches or simulated in models only. It is also possible to observe them in living tissue. The objective of this virtual lab is to observe the effect of changing outside conditions on the living cells of Elodea canadensis, an aquatic plant.

The interactive PowerPoint-Show “Virtual Lab: Plasmolysis and Deplasmolysis” offers microscopic photographs of cells of Elodea canadensis during plasmolysis and deplasmolysis.

Furthermore, this bundle of documents contains an accompanying worksheet as well as the solutions for this worksheet.
