Osmosis in Plant Cells Aim: To investigate the effects of different water potential sucrose solutions, on the size and weight of potato cylinders over the period of 48hours. (Plant Cells) Prediction: From my background knowledge I predict that as the concentration of the sucrose solution that the potato cylinder is placed in increases, the size and weight of the potato cylinder will decrease over the period of 48hours, and vice versa, if sucrose solution concentration decreases, the potato cylinder should swell up and its size and weigh will increase. These predictions have scientific explanations. When a potato cylinder is placed in a high concentration sucrose solution where little water or no water at all is added, the potato cells under go a process called plasmolysis. Plant cells, in this case potato cells have a thick cell wall which is freely permeable and supports the cell; inside this cell wall is the protoplast which...
