Biology Assessment Practical Isabelle Litwin Title: Permeability of Cell Membrane in Beetroot Cells Aim: To find out how temperature affects the cell membrane permeability of beetroot cells Theory/ Background: Permeability of a cell to solutes in an aqueous medium depends upon the physical and chemical make-up of the membrane. The maintenance of the living cell depends upon the continued presence and functioning of a selectively permeable membrane. If the membrane is altered in any way, this may have an effect on its permeability and therefore the properties of the cell of which it is a part. Irreversible changes in the permeability of the membrane usually lead to the death of the cell. The cell membrane provides a boundary between the cell's inner environment and its surrounding outer environment. It allows different substances to pass through at varying rates, this is described are differentially permeable. It controls things such as sugar concentration, ion...
