In this experiment, different concentrations of sucrose are first prepared. Then, cylinders of potato (Solanum tuberosum) tuber are made using a cork borer, which are then trimmed to remove the skin and be of the same length. The cylinders are blot dried and weighed prior to being placed in each of the test tubes containing the sucrose solution. After 20 minutes, the cylinders were removed from the solution, blot dried, then weighed again. Study the results of the experiment shown in Table 1. Table 1.

Transcribed Image Text:In this experiment, different concentrations of sucrose are first prepared. Then, cylinders of potato
(Solanum tuberosum) tuber are made using a cork borer, which are then trimmed to remove the
skin and be of the same length. The cylinders are blot dried and weighed prior to being placed in
each of the test tubes containing the sucrose solution. After 20 minutes, the cylinders were
removed from the solution, blot dried, then weighed again. Study the results of the experiment
shown in Table 1.
