From Table 1, there was a decrease in mass for bags A and B. This means that osmosis took place, and the water molecules were moving from the sugar solution to the sucrose in the culture dish. This is because the the sugar was more concentrated outside of the dialysis bags, causing water to move down the concentration gradient and outside of the bag. The masses of bags C and D increased. Osmosis took place here as well, since the solutions had different concentrations from that of the concentration of the solutions in the culture dish. The results in Table 2 depicts how the masses of the dialysis tubes changed with time for a total duration of one hour. The masses of tubes A and B were seen to be reducing with time. This shows that molecules
