The Effect Of Sucrose Concentration On Potatoes

Potatoes The initial weights of the potato cubes ranged from 0.93-1.04 grams from the solutions containing AgNO3 (Table 1). Graph one depicts the correlation of percent change in weight for each sucrose concentration with AgNO3 added. The initial length of the potato cylinders were 2cm as depicted in table two. Graph two depicts the correlation of percent change in length in different sucrose concentrations. The initial weights for the solutions lacking AgNO3 ranged from 1.0-1.7grams (Table 3). Graph three displays the correlation for the percent change in weight for a solution lacking AgNO3 in different sucrose solutions. The initial lengths of the cylinders were 2cm (Table 4).Graph four depicts the correlation for the percent change in length in a solution without AgNO3 in differing sucrose solutions. Even though the weights were not consistent throughout the potato cubes, this had no effect on the results, because the experiment focused on the change in the weight. The final weights for the potato cubes had a range from 0.75-0.99 grams for the solutions that contained AgNO3 (Table 1). The final weights for the potato cubes without AgNO3 ranged from 0.70-1.8 grams (Table 3 ). The final length of the cylinders ranged
The results showed that the sucrose solution of 0.0M in the solution lacking AgNO3, showed the cells expanded, to the point of explosion from a hypotonic solution( Figure 1). Incipient plasmolysis occurred in the solution that contained AgNO3 in the sucrose concentration of 0.4M (Figure 2). In addition, the Elodea cells seemed to shrink as the sucrose concentrations’ increased without AgNO3. Therefore the results were that with the addition of AgNO3, osmosis was not inhibited. The internal osmotic pressure at different sucrose concentrations was 0 for 0.0M, 2.43 for 0.1M, 4.85 for 0.2M, 7.28 for 0.3M, 9.71 for 0.4M, 12.14 for 0.5M, 14.56 for 0.6M, and 24.27 for 1.0M (Table
