... of triglycerides known as phospholipids. In the cells of a beetroot plant, a substance called anthocyanin is contained within the cell membrane. If a cell is damaged in a beetroot plant and the membrane is broken, the anthocyanin 'bleeds' from the cells like a dye. As we are experimenting with the effects of temperature on the membrane, we will place the samples of beetroot into a water baths of varying temperatures and measure the colour change in the water. Temperature is just one of the possible variables. The dependant variable in this experiment is colour change in water caused by anthocyanin leakage. This will be recorded using a colorimeter and the results can be expressed in units of parts per million (ppm), milligrams per liter (mg/l), grains per gallon (gpg) or other useful and appropriate scales like the percentage used. Aim: This experiment aims to determine what effect an increase ...
