[tags: Biology Biological Lab Experiment Essays] - Investigate the Effect of Temperature on Cell Membranes and Membrane Structure If you read a recipe for cooked beetroot it will usually recommend that you don’t remove the outer skin of the beetroot and don’t cut off al the stalk and root if you want to avoid getting lots of red dye in the cooking water.

Beetroot contains red pigments called betalains, located within the cell vacuole.

The water can move between the potato and the solution but the sugar can’t because the molecules are too big to pass through the membrane.

The water will move between the solution and the potato....

Doing this could lead to being disqualified from all the subjects that you are taking....
