Isotonic Point of Potatoes - Biology Lab Report
Topic: Chemicals of Life
To find the isotonic point of potato (Solanum tuberosum) by varying the concentration (M) (+/- 0.06 M) (0.10,0.15,0.20,0.25,0.30 M) and measuring the change in length of potato strips (cm) (+/- 0.01 cm).
Isotonic Point: The isotonic point is the point where the concentration of the solution is the same as the concentration of the cell. It means that there are equal amounts of 'free' water (not bound to solutes) in the solution and the potato.
Potato: A plant tuber, Solanum tuberosum, eaten as a starchy vegetable, particularly in the Americas and Europe
1) Concentration of Glucose solution (M) (+/- 0.06 M) (0.10, 0.15, 0.20, 0.25, 0.30)
1) The change in mass and length of the potato chips (cm) (+/- 0.01 cm)
Method of control
Initial length of the potatoes strips used for the experiment (cm) (+/- 0.01 cm)
The potatoes will be cut to a specific initial length before using them in the experiment using an accurate measuring instrument and
