Prediction Osmosis is defined as the passing of water from a high concentration to a lower one through a semi-permeable layer, in an attempt to try and even out a water concentration. Here is an example of water passing across the concentration gradient: To prove the theory of Osmosis we are using chips of the vegetable potato. Plants naturally have semi-permeable skins to allow the passage of water and each plant cell has a vacuole, which is used to store water. Here is...
