Original application practice · 14 indicative marks
Answer without the guided prompts, then review the science and working.
These are our practice questions and indicative marks, not examination-board questions or an awarded grade. The data are shared with guided practice; a case you have already studied is not an unseen test.
Comparable plant-tissue cylinders were immersed for the same interval in sucrose solutions at the same temperature. The table gives mean masses from three independent cylinders at each concentration. These original classroom data describe this tissue and method; no water-potential calibration is supplied.
| Sucrose concentration / mol dm⁻³ | Initial mean mass / g | Final mean mass / g |
|---|---|---|
| 0 | 2.00 | 2.18 |
| 0.2 | 2.00 | 2.06 |
| 0.4 | 2.00 | 1.94 |
| 0.6 | 2.00 | 1.80 |
| 0.8 | 2.00 | 1.68 |
