Cell Membranes: Diffusion and Osmosis
Create a model cell to observe diffusion through a membrane.
What molecules can pass through the pores of a cell membrane? Create a model cell and perfom tests to determine what molecules diffused into or out of your model cell.
How does osmosis (diffusion of water) affect plant and animal cells placed in different environments?
- Predict what molecules might pass through the cell model membrane.
- Perform lab tests to determine if your predictions are correct.
- Observe what happens when plant cells are placed in environments that have different salt concentrations.
- Explain how diffusion and osmosis can be applied to real-world scenarios.
