Three Lab Groups Carried Out an Experiment to Identify the Correct

question 15

Multiple Choice

Three lab groups carried out an experiment to identify the correct molarities for five solutions.Each unknown contained one of the following sucrose concentrations: 0.0 M,0.2 M,0.4 M,0.6 M,0.8 M,and 1.0 M.Each data entry represents the average of 3 sample replications of 1 cm3 sweet potato cubes expressed as percent change in mass after an overnight (24 hr) soak in the unknown solutions.From the data given,which statement most accurately describes what is occurring in response to a particular unknown solution.

• A)Unknown solution E contains the highest concentration of sucrose and the change in mass is due to the active transport of sucrose into the cell in exchange for water molecules.
• B)Osmosis of water molecules from unknown solution A likely caused the increase in mass observed.
• C)Passive transport of sucrose out of the potato cells explains the change in mass observed for unknown solution F.
• D)Unknown solution C represents a sucrose molarity slightly lower than the molarity of sweet potato cells, thus water is transported out of the cells.
• E)Transport of Na+ to the outside of the cell is likely have caused the decrease in mass observed for unknown solution C.
