WebA cell membrane is similar to dialysis tubing. In activity A, dialysis tubing was used to model diffusion across the cell. The glucose in the dialysis bag went from clear to blue with a negative test result before and after and the iodine-potassium iodide in the cup went from dark red to copper colored. The results were positive before and after.
