Pre-lab Quiz Results
You scored 100% by answering 4 out of 4 questions correctly.
1 Which of the following is true of osmosis?
You correctly answered: It is a type of diffusion.
2 Which of the following occurs when a hypertonic solution is added to cells?
You correctly answered: The cells shrink.
3 The variable that affects osmotic pressure is
You correctly answered: the concentration of nondiffusing solutes.
4 The net movement of water would be into the cell in a You correctly answered: hypotonic solution.
Experiment Results
Predict Questions
1 Predict Question 1: What effect do you think increasing the Na + Cl- concentration will have?
Your answer: increased osmotic pressure.
2 Predict Question 2: What do you think will be the pressure result of the current experimental
conditions?
Your answer: no change in pressure.
Stop & Think Questions
1 Why do you think there is no pressure change?
You correctly answered: Sodium is able to diffuse through the pores.
2 Why do you think there was no pressure change?
You correctly answered: There is no net movement of water because the solute concentrations are
the same.
