Investigating the water potential of potato cells
Introduction
I am going to be doing an experiment to try and measure the water potential of potato cells. The net direction of water movement in a cell depends on whether the water potential of the cell solution is more negative or less negative than the water potential of the external solution.
Aim
To measure the water potential of potato cells in different concentrations of sucrose solution.
Equipment
Reasons for choosing equipment
- 18 test tubes are used to place in the different concentrations of solution with the potato
- Pipette is used to measure out solutions
