GCSE Biology Coursework Planning For my GCSE biology coursework, I am going to conduct an investigation into the effect of different concentrations of sucrose solutions on potato tissue. Apparatus 18 test tubes A test tube rack Cork borer A potato Balance Prediction As the concentration of the sucrose solution increases, the mass of the potato cylinders will decrease. This is because osmosis is taking place. Osmosis is the diffusion of water from a higher concentration of water to a lower concentration of water through a selectively permeable membrane. When the potato in is put into distilled water, it will get bigger as water will enter its cells by osmosis. This is because the water is more concentrated outside the potato rather than inside the potato. The water will stop when the potato cells are turgid. When the potato is put into the 1M sucrose solution, it will get smaller as water will leave its cells by...
