Biology SC1: How does the concentration of sucrose affect the weight of pieces of potato after osmosis has taken place? Aim The aim of this is experiment is to investigate how much sucrose is in a potato. We are going to investigate the effect of different concentrations of sucrose on the weights of pieces of potato after osmosis has taken place. Prediction I predict that the less concentrated the solution of sucrose is, the greater the weight of the potato will be. I predict this because osmosis is the movement of water from a region of high water concentration to a region of low water concentration through a semi-permeable membrane i.e. the cell wall of the potato. If the concentration of water inside the potato is high then the water will pass out through the cell wall, decreasing the weight of the potato. If the concentration of water outside of the potato is...
