    The purpose of this experiment was to test the tonicity of potato cells. The potato cells were placed in different test tubes with water and were left there for 15 minutes. The percent change in mass is then used to determine if the cells lost or gained water‚ therefore determining the tonicity of the cell. Although it was a brief short time‚ the final results showed that the more water the potatoes were placed in‚ the more hypotonic the potato becomes. Tonicity is stated to be the state of a solution
