1. Plasmolysis in Plant Cells
Visual Demo

2. Predict – What will happen to plant cells placed in salt water?
Form a hypothesis predicting what will happen to a plant cell when placed in a 1% salt solution and a 5% salt solution.

3. Observe
Watch the videos that demonstrate cells placed in 1% and 5% salt solutions.

4. Diagram
Make a diagram including labels that shows what happens to the plant cell in both the 1% and 5% solutions. You may need to use colored pencils to clearly show what is happening.

5. Conclude
1. What happened to the cells soaked in the 1% salt solution? Why do you think this happened?
2. What happened to the cells soaked in the 5% salt solution? Why do you think this happened?
3. What would happen to an animal cell if it was placed in a 20% salt solution?
4. Why can’t a salt water fish live in a freshwater water lake? Use you science terms to explain.
