Biology GCSE Science 1 Assessment Investigating Osmosis Planning Experimental Procedures The aim of this investigation is to find what factors would affect the size of a potato cylinder, when it is left in sucrose solution. I have chosen to investigate how concentration affects the size of a potato cylinder when placed in a sucrose solution Prediction I predict that the lower the concentration of the sucrose solution, the larger the potato cylinders will be. The higher the concentration of the sucrose solution the smaller the potato cylinders will be, this is because of osmosis. Osmosis is a special case of diffusion, where water moves from a high concentration to a low concentration, across a semi-permeable membrane. When the concentration of the sucrose solution is high, water inside the potato cylinder diffuses across the potato cell membrane, to the sucrose solution, this is to balance the solution out, when this happens the cylinder shrinks because it...
