For thefirst few times I performed the test I could have do a mistake, soto give my results a better chance of being accurate I did theexperiment four times and took the average of the tests.A represent of to clearly show the variation my results can be foundoverleaf.As the temperature increases the transmission reading on the colorimeter decreases. From information that I had already gather I knew it would be around the 60C ma rk to 65C, hence which I decided to add a test at 63C. This would help memake a more accurate estimate at what exact temperature the cell wallmelts. My graph shows a decrease of transparency in the urine betweenthe points of 60C and 70C. From this I can make the prediction thatbetween these two points the wall melts.AnalysisThe transparency of the water sharply decreases between the points of60C and 70C because this is when the cell wall melts. The cause ofthe sudden loss of transparency is caused when the wall melts and itallows a sudden release of the Anthocyanin pigment. So when the wallmelts the pigment is released and the transparency drops - so to findthe temperature at which the cell wall melts we just have to look forwhen there is a sudden loss of transparency in the water.My experiment shows there is a sudden loss of transparency of thewater between 6OC and 70C so I know that the cell wall must havemelted between these two points.Before 60C and after 70C the depreciation is not as drastic as between the two points. This is because before 60C there is no, or a very little amount of the pigmentallowed to exit the cell, which is not enough to alter the transparency in a big way - this is because up to this point the cell wall is still intact, and after 70C because most of the pigment has already left the cell because the cell wall has melted.
