Describe the practical which investigate the effects of osmosis on plant tissue in six steps

Firstly the potato is peeled because the skin can affect osmosis and three cylinders are cut out of it using a cork borer which ensures all the cylinders are equal in diameter Then a scalpel is used to cut the cylinders to an equal length (usually around 3cm) Next the length is mesusrrecusung a ruler and the weight is measured using a balance Now the cylinders are placed into test tubes and 10^3cm of 0.5 molar sugar solution is adde to the first test tube, 10^3cm of 0.25 molar sugar solution is added to the second test tube and distilled water is added to the third Then the potato is left overnight to let osmosis take place The potato is rolled in tissue kaisee to remove surface moisture Lastly the length and the mass of the clingers are measured again and the percentage change from the original values is calculated - equation to calculate percentage change =( change in value / original value ) x 100
