Membrane permeability experiment

Can be done using temperature or alcohol concentration 5 water baths from 0 to 50 cut 5 beetroot cores must be from the same source and cut to the same length rinse off the beetroot so excess membrane/pigment is washed away place beetroot in test tubes in each water bath and wait for 30 mins set the colorimeter to blue-green filter syringe a sample of each beetroot solution into a cuvette place each cuvette sample into the colorimeter and record the absorbance value after each reading zero the colorimeter with a cuvette of distilled water repeat these steps to get a mean average reading of absorbance
