Osmosis in potatoes. Osmosis is the diffusion of water from a weak solution (lots of water) to a strong solution (little water) through a selectively permeable membrane, going down a concentration gradient. A plant cell has a weak solution in it but not as weak (or pure) as water. When placed in water then, a plant cell becomes turgid because the water diffuses into the cell because there is a lower concentration of water inside the cell. Therefore, when put in a sucrose (sugar) solution, the plant cell becomes flaccid (or plasmolysed), this is because the solution in the cell diffuses out where the concentration of water is lower. Potatoes are made up of plant cells because it is a type of plant for the reason that it comes from the ground. Therefore, when put in water it will take it in by diffusion and become turgid and then in...
