Usman Omid Biology IB 1A The Effect of Temperature on Beetroot Membranes _Aim_ This practical will test the effect of temperature on the integrity of the membranes‚ _Introduction_ The cells of beetroot contain a pigment called betalain in their vacuoles. It is kept inside the cells by the membranes. If these membranes are damaged‚ then the betalain leaks out. The amount that leaks out can be assessed‚ as the leaked out pigment will color the water surrounding the cells. This information can

Investigating Effects of duration of heating on permeability of beetroot cell membrane Introduction: Cell membranes contain many different types of molecules which have different roles in the overall structure of the membrane. Phospholipids form a bilayer‚ which is the basic structure of the membrane. Their non-polar tails form a barrier to most water soluble substances. Membrane proteins serves as channels for transport of metabolites‚ some act as enzymes or carriers‚ while some are receptors
