6. The graph below represents the mass change of ten potato tuber “chips” in distilled water (blue) and ten potato chips in 15% sucrose (red) measured every 10 minutes for 60 minutes.The chips were all cylinders of 50 mm length and 10 mm diameter. Before each measurement, the chips were dried carefully. After measurements were taken, they were replaced in the correct solution. The length of the chips at 0, 20, 40 and 60 minutes were also measured.
