Strips of plant tissue were placed in sucrose solutions of different concentrations. The percentage change in mass after 30 minutes is shown:
0.1 mol dm⁻³: +8%
0.3 mol dm⁻³: +3%
0.5 mol dm⁻³: 0%
0.7 mol dm⁻³: −5%
At which sucrose concentration is the water potential of the solution equal to that of the cell sap before immersion?
0.1 mol dm⁻³: +8%
0.3 mol dm⁻³: +3%
0.5 mol dm⁻³: 0%
0.7 mol dm⁻³: −5%

- 0.1 mol dm⁻³
- 0.3 mol dm⁻³
- 0.5 mol dm⁻³
- 0.7 mol dm⁻³
