nature vs nurture arguments nurture essays - 3. The betacyanin pigment of beetroot is normally sequestered in the vacuole of the beet root cells. Of course, if the beetroot is cut, cells are sliced open and the pigment spills out. However, if the membrane is altered (phospholipid bilayer + proteins) more subtly, leakage (diffusion) of betacyanin is induced. The graph shows the colorimeter readings increase as the temperature increases, they increase by the most at higher temperatures. This is shown by a smooth curve. This means that the beetroot samples release more dye at higher temperatures. This is because higher temperatures cause the membrane structure to break down.

Dec 10, · In grade 11 I did a Biology EEI (extended experimental investigation) on the effects of environmental stress on cell membranes, using beetroot as a test subject. Beetroot cells contain brightly coloured betalain and anthocyanin pigments in a vacuole, thus the damage to the membrane can be measured by the amount of pigment leaked out of the beetroot. In the cells of a beetroot plant, a substance called betalins is found in the membrane vacuoles, which gives beetroot its red colour. Normally the pigments cannot pass through the membranes but at higher temperatures the cell becomes damaged and the betalins will ‘bleed’ from the cells. pitru devo bhava essay in telugu
