Aim I will be carrying out this experiment to investigate the effects reflected on a potato tuber; which is left in sugar solutions of various concentrations. Prediction I predict that the more dilute (the solution with more water than sugar in it) will result with the potato's mass increasing. I base this prediction on the knowledge I have about osmosis. Osmosis is the term given for the process of water passing through a semi-permeable membrane from the less concentrated solution to a more concentrated solution. If the potato tuber has a higher sugar concentrate than the sugar solution surrounding it, osmosis will take place into the potato, causing the potato in the solution to swell. This is because the plant cells; which make up the potato have become turgid, So that the cytoplasm is pushing outwards onto the cell wall. (Please refer to diagram 2 on separate sheet) To find out how much...
