Investigation Movement of Pigment through Cell Membranes Aim The aim of the investigation is to identify the effect of temperature of the movement of pigment through cell membrane of beetroot cells. Prediction and Reasoning I predict that the temperature will effect the movement of the beetroot pigment through the cell membrane. I believe an increase in temperature would result in an increase in the amount of pigment being released out of the cell. I base my prediction on the fact that an increase in temperature would provide the pigment molecules with more kinetic energy and therefore the rate of diffusion will increase. The increase in temperature would also denature (damage or change the characteristics of) the cell membrane resulting in more pigment being lost. Allowing the pigment to diffuse more rapidly throughout the two dimensional surface of the membrane. In the diagram the pigment from the beetroot (section A) would pass more readily into the...
