buzz Moses is a type of diffusion that occurs in all living things through liquids to create a balance of minerals or nutrition himself through semipermeable membranes the semipermeable membrane is a skin on a cell that only allows some molecules to pass in this case it allows water to pass the reason this experiment shows once Moses is because it caused Moses didn't exist when both results would be in sync even though one glass of soul water in and the other has normal water rouvaun's racism is real and applies to all living things the results are different one potato is crisp and hard and it becomes turgid well the others flexible and soft and it becomes flaccid the reason the saltwater potato becomes flexible is because the salt water attracts the normal water and the potato salts and when there isn't enough water in the cell since water makes up the structure of the potato the structure becomes weak and therefore flexible the reason that turns brown is because they extracting so much water from the cells damages them which make them release an enzyme that's something that's been difficult amical reaction in this case it speeds up the Browning of the potato but catechol oxidase catechol oxidase then combines with oxygen which causes the chemical reaction that makes the potato turn brown there isn't a normal water potato it gets bigger is because there's a higher concentration of water outside the potato in the glass full of water then in the potato when there's a higher concentration of water outside than inside something the water moves from the high concentration to a low concentration until it's evenly spread out that's also called diffusion this means that water from outside the potato goes into the potato cells and makes them become bigger the reason the normal water potato doesn't become flexible is because that water makes up the structure of the potato so when there still is water in potato or a lot of water in this case it doesn't lose its structure and become flexible to conclude osmosis is a type of diffusion where molecules diffuse through water through semipermeable membranes of cells until they're evenly spread out
