Starch

As we observed in the Diffusion Through a Membrane lab, starch cannot pass through a semi-permeable membrane. We know this because the solution surrounding the cell we constructed remained amber, instead of turning purple. Starch is too large a molecule to pass through the membrane of a cell.
