Starch and glucose , combine both into a bag made of synthetic membrane and out the bag in a beaker of iodine solution . Allow it to diffuse across the membrane and then test it to see if the substance has crossed the membrane .
The diffusion of the glucose can be tested by the Put the starch and glucose solution into a dialysis tube and put the bags in the iodine solution.
Wait for the time being so the solution can diffuse cross the tubing and measure or weigh the last mass that can be compared to the compared group check if the glucose is diffusing or not.
