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. WebJun 19, 2024 · DIFFUSION AND OSMOSIS. Molecules in air and molecules in liquids are in motion, and they tend to become evenly mixed. When a person wears a fragrance, it is this natural mixing process that allows others to smell the fragrance. When you put food coloring in a glass of water, it gradually moves out from the center and colors all of the water.
