MATERIAL AND METHODS Stability of cell membrane using pH For the lab experiment for testing the stability of beet cell membranes using pH‚ many materials were used as follows. Obtaining a beet we punch out cores‚ using a cork borer. After washing the cores we put each one inside a separate test tube‚ and added a different pH solution in each one. After 3 minutes in these exposure solutions‚ we took the beet out with a dissecting needle. Then transferred each beet to a separate test tube containing
