An investigation to show the effects of temperature on the rate of diffusion Aim: This experiment aims to determine what effects temperature has on the rate of diffusion on the plasma membrane of a beetroot sample. Hypothesis: Evidence found from earlier research has shown that as temperature increases, the plasma membrane breaks which causes the cytoplasm, and other substances contained within the membrane to leak out. This causes the colour pigment to be released. The rate at which the colour pigment is dependent on the temperature of the solute for example higher temperature means diffusion occurs more quickly. Background Research: Substances are exchanged between cells and their surroundings, across cell surface membrane. Cells obtain their requirements to function by allowing molecules to move across membranes through methods such as diffusion. Diffusion is the process by which a substance moves from a region of high concentration, to a low concentration of the same substance. Diffusion can also...
