For the diffusion and osmosis lab, you gathered data based on changes in the weight of model cells. to design your experiment, you made educated assumptions about what would pass through the dialysis tubing membrane, and what would not? using knowledge you gained during the macromolecules lab, give examples of how you could tested these assumptions in relation to movement of starch, sugar and proteins. these examples do not need to relate to your group's experiment.
