    It's the practical that tests the effect of temperature on membrane permeability and it uses beetroot and uses a water bath and heats up test tubes at different temperatures and you put the beetroot in and then use a calorimeter to see how much light is transmitted in different test tubes with different temperatures, testing the permeability of the beetroot at different temperatures.It justs asks what the limitations are of the experiment.
