effect of temperature and chemicals on a plasma membrane
The Effect of temperature and chemicals on a Plasma Membrane (beetroot) This experiment aims to determine what effect an increase in the surrounding temperature and the presence of the chemicals distilled water, acid, alkali and alcohol have on the plasma membrane of beetroot. In the cells of a beetroot plant, a substance called anthocyanin is contained within the plasma membrane. ... If a cell is damaged in a beetroot plant and the membrane is broken, the anthocyanin bleeds from the cells like a dye. It is this characteristic that enables us to find out which conditions affect the cell membrane. ... The test variables are temperature and chemicals.
