How does the temperature affect the beetroot membrane?
... 3. the equipment that was used were also kept same in order to keep the experiment fair. Although the results that were produced clearly illustrate that the prediction made was correct. However there may have been some problems enquired when carrying out the experiment. a. When cutting 21mm long cylinders into equal discs, they should have been cut perpendicularly. If not then the surface area of one piece may be bigger than other and hence the permeability of the piece may increase the permeability. If all 56 discs were cut together and then chose 7 discs at random, the different cylinder may have been different permeability and thus may affect the end-results. If for example some of the cylinders were cut from the root side (base) of beetroot and others from the opposite side, the permeability may also be affected because different location of the cylinder may affect the leakage of the pigment. b. When washing the beetroot cylinders in tap water, it might be washed at different extent. If the washing was stopped before the entire colour leaks out, hence it will influence the permeability. c. When rinsing the impaled cylinders, the discs may not have been washed in both, tap water and distilled water. Even though this is not the major effective error, it may influence the end-results. d.
