Planning Introduction Osmosis is the passage of water molecules from a weaker solution into a stronger solution, through a partially permeable membrane. In this case, the tiny holes in the membrane of the potatoes will allow the water molecules to pass through in and out of the solution and the potato, depending on the concentration gradient of the two substances. So in this case, when the water concentration is lower in the tissue, the water will go inside the tissue of the potato, and the potato will grow in length, and if there is very little difference in the two water concentrations, there shouldn't be such a big change in length. If there is a higher concentration of water in the potato, the water will go out of the potato. Water molecules have random kinetic energy meaning they move around where they want and wherever they want. The potato, cut up into pieces,...
