A potato strip is placed in a 0.20 mol/dm³ salt solution for 30 minutes. Its mass decreases by 8%. What does this show about the water potential of the potato cells compared to the solution?
- Cells and solution have equal water potential.
- Cells have lower water potential than the solution.
- Cells have higher water potential than the solution.
- Water potential is unrelated to the change in mass.
