I looked at the different parts of passive transport: diffusion and osmosis and recognized how they both follow the concentration gradient from an area of ​​high to low concentration. My assumption for procedure 1, that all dialysis tubing would be in a hypotonic environment, was correct. This occurred because the tubes were placed in a glass filled with water, meaning there was a higher concentration of water than solute, causing the water to diffuse into the cell after 30 minutes. When water diffuses into the cell, this causes the cell to expand. Some possible errors that may have been made in the experiments would be failure to pay attention to the times the tubes and potatoes were in the solutions, inaccurate measurements when collecting the solutions, and differences in the size of the potatoes which may have had an effect on the results. This experiment relates to AP Biology Big ideas and Science Practices because by observing cells, I attempted to maintain balance or homeostasis by being in an isotonic environment, while also using representations and models to communicate scientific theories when using tubes dialysis to form as cells. I have correctly calculated the math using the percent change formula and feel I have gained more knowledge by questioning and forming my initial hypothesis for each
