In your experiment on osmosis and diffusion using dialysis tubing, you can create the following cell conditions:

  1. Osmosis Conditions:

    • 0% glucose solution (pure water)
    • 1% glucose solution
    • 15% glucose solution
    • 30% glucose solution
  2. Diffusion Conditions:

    • Starch (inside the dialysis tubing)
    • Water (surrounding the dialysis tubing)
    • Starch + Glucose (inside the dialysis tubing)
    • Water + Glucose (surrounding the dialysis tubing)
    • Water + Starch (surrounding the dialysis tubing)
    • Pure water (as a control condition)

These combinations enable you to observe both osmosis (water movement due to glucose concentration gradients) and diffusion (movement of starch and glucose across the dialysis membrane). Each condition provides a different scenario to study the effects of concentration gradients on the movement of substances.
