Stressing Membranes: Beet LabThis graph depicts the colorimeter apprises obtained for samples of common beetroot cores from to all(prenominal) one of the diverse leaven tubes measured at incompatible temperatures. underground 1 was at -5C, electron tube 2 was at 5C, piping 3 was at 20C, Tube 4 was at 40C, Tube 5 was at 55C,and Tube 6 was at 70C. The tercet sets of averages measured followed a similar curve, scantime slowly, rising and stay constant, and then dropping down, but preceding(prenominal) the initial values. The colorimeter indicated how much pigment was present in the 10mL buffer peeing the core was kept in, and the lower the value the more betacyanin was released from ruptured carrells. The fixed core was the lowest value, while the tick off temperatures fancyed around itsy-bitsy to no release of pigment. The highest temperature, at 70C, was heavily affected as well. This graph depicts the colorimeter results of the water the beet core was stored in after being treated to assorted assiduitys of acid solvent. Concentrations of vitamin C%, 50%, 25%, and 1% were added to the beet core test tubes to measure the degree of damage to the cell membrane and the centre of betacyanin that was released from the cell.
Tubes 1-4 show methyl group 100-1% concentration values, Tube 5 shows distilled water, Tubes 6-9 show ethyl, Tubes 10-13 show propyl, Tubes 14-17 show butyl, and Tubes 18-21 show acetone in rank from 100% to 1% respectively. Butyl was the minimal possible, followed by acetone, while methyl and propyl were the least affected. DiscussionThis laboratory demonstrated the effects of different temperatures and pH acid concentr! ations on beet cells. The results we obtained were somewhat wrong or presented errors, but outliers were remote and thus a comparatively expected, average trend was shown for from each one variable tested, and the given results greatly...
