Beet Cells Lab Report Essay
Membranes are an important feature of plant cells and they act as a barrier that separates the interior of the cell from the external environment (Campbell et al., 2008). Each membrane layer is composed of a phospholipid layer, which is semi-permeable and possesses the ability to control the movement of diffusion. Within the centre of a cell, the vacuole that is responsible for storage and the maintenance of osmotic balance can be located. In this study, we are using beets to study these cellular structures. Beet is a plant whose cells contain a characteristic red pigment, called betacyanin. It is located in the vacuole, which is …show more content…
Results In our experiment, we observed that the samples in temperature –5°C and 70°C contained the highest concentration of betacyanin (Figure 2). To obtain these results, we used the standard curve for betacyanin (Figure 1) to figure out the concentration, since the value of betacyanin absorbance could be measured using the spectrophotometer.
From the graph (Figure 2), between the temperature of 4°C, 42°C, 55°C, it was observed that the ranges of concentration was narrow, which shows the increase concentration was quite steady. Generally, an increase of temperature would cause an increase in absorbance of
