Movement Across the Cell Membrane LAB Title Challenge: “How can I illustrate diffusion and osmosis using a model cell?” Procedure: – Cut out and tape or paste the procedural steps into this section of your lab notebook. – Make a labeled sketch of your experimental set-up.

Movement Across the Cell Membrane LAB Data: – Follow the directions in procedure step #10 to set up your NEAT data table (rulers are available!) – Record your data. Use units. – Calculate % change in mass. Record.

Cell Membrane LAB – Conclusion Explain your findings in paragraph form. Be sure to address the challenge. Include data in your conclusion.

Cell Membrane LAB – Analysis Questions 1.In comparing beaker “A” with beaker “B”, what was the manipulated variable? 2.In setting up beakers “A” and “B”, what were 4 factors that you controlled? 3.Explain the results using labeled sketches. 4.In Type I diabetes, insulin is not produced and the body’s liver cells are not instructed to uptake glucose. Glucose remains in the blood. Which beaker represents someone with Type I diabetes? How are this person’s cells affected?
