Hypothesis(Based on what you’ve learned in the pre-lab materials, write and If/Then statement regarding the outcome of this experiment.): If a plant cell is in a salt solution, then the plant cells will shrink due to loss of water to osmosis.Table 4: Water Displacement per Potato SamplePotatoTypePotatoObservationsSampleInitialDisplacement (mL)FinalDisplacement (mL)NetDisplacement (mL)RedSmooth, redskin, markedonly withgrowth divots,firmA (water)79-2RedSmooth skin,marked onlywith growthdivots, firmB (NaCl)761RussetBrown, roughskin, somebruising,dirty, firmA (water)1213-1RussetBrown, roughskin, somebruising,dirty, firmB (NaCl)12111Claim(What are the results of your experiment?): Cell wall structure was compromised by osmosis of water from cell interior into brine solution.Evidence(What data did you collect that supports your claim? Explain the meaning behind the data and the calculations.): The negative net displacement of samples in water show that water ©eScience Labs, LLC 2018 Diffusion and Osmosis

Post-Lab Questions 1.How did the physical characteristics of the potato vary before and after the experiment? Did it vary by potato type? 17. What does the net change in the potato sample indicate? 18. Different types of potatoes have varying natural carbohydrate concentrations. Explain how this may influence the water potential of each type of potato.
