Essay / What is diffusion diffusion and osmosis
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 tubes would be in a hypotonic environment, was correct. This happened because the tubes were placed in a beaker of water, meaning there was a higher concentration of water than the solute, causing the water to diffuse into the cell after 30 minutes. When water diffuses into the cell, it expands. Some possible errors that could have been made in the experiments would be lack of attention to when the tubes and potatoes were in the solutions, inaccurate measurements when collecting the solutions, and differences in the size of the potatoes. land that could have had an effect. on the results. This experience relates to AP Biology Big Ideas and Science Practices because by observing cells, I tried to maintain balance or homeostasis by being in an isotonic environment, while using representations and models to communicate scientific theories when using dialysis tubes to form cells. I calculated the math correctly using the percent change formula, and I feel like I gained more knowledge by questioning and formulating my original assumption for each
