Experiment 4: Osmosis - Tonicity and the Plant Cell Table 7: Water Displacement per Potato Sample Post-Lab Questions 1. How did the physical characteristics of the potato vary before and after the experiment? Did it vary by potato type? Click here to enter text. 2. What does the net change in the potato sample indicate? Click here to enter text. 3. Different types of potatoes have varying natural sugar concentrations. Explain how this may influence the water potential of each type of potato. Click here to enter text. 4. Based on the data from this experiment, hypothesize which potato has the highest natural sugar concentration. Explain your reasoning. Click here to enter text. 5. Did water flow in or out of the plant cells (potato cells) in each of the samples examined? How do you know this? Click here to enter text. 6. Would this experiment work with other plant cells? What about with animal cells? Why or why not? Click here to enter text. 7. From what you know of tonicity, what can you say about the plant cells and the solutions in the test tubes? Click here to enter text. 8. What do your results show about the concentration of the cytoplasm in the potat cells at the start of the experiment? Click here to enter text. 9. If the potato is allowed to dehydrate by sitting in open air, would the potato cells be more likely to absorb more or less water? Explain.
