SCIENCE: Osmosis In Potato Cells Task In this experiment, our task was to investigate the effect osmosis had on the mass of a potato chip. Research: Osmosis is when the molecules move around a solvent, through a semi-permeable membrane, lowering the concentration of a solute on the other side of the membrane. The purpose of this is to match the two sides of the membrane, so they are balanced. This is caused by osmotic pressure, an irreversible type of diffusion. This is when molecules jump from one place with a high concentration to another with a low concentration. Diffusion is important for many things, especially in the human respiratory system, when the alveolar membrane of the lung separates the carbon-dioxide filled blood with the oxygen-rich air. Plan: To determine the rate of osmosis in a potato chip, we can treat a number of different chip specimens with different solutions. These are distilled water, 5% sucrose solution,...
