Because we are experimenting with the effects of temperature on the membrane, we will place the samples of beetroot into beakers (water baths) of varying temperatures and measure the colour change in the water. Hypothesis: The purpose of a plasma membrane is to control the transport of substances moving into and out of a cell. In the cells of a beetroot plant, a substance called anthocyanin is contained within the plasma membrane. It is anthocyanin, which gives the beetroot its red/purple colour. If a cell is damaged in a beetroot plant and the plasma membrane is broken, the anthocyanin "bleeds" from the cells like a dye. An increase in temperature will damage and denature the plasma membrane and cause the cytoplasm and other substances contained within...
