Osmosis
Biology · Secondary 4 · Hard · Osmosis
A student places identical potato strips into sugar solutions of different concentrations and measures the percentage change in length after 3 hours. The graph shows that at 0.10 mol dm⁻³ the strips gain length, at 0.40 mol dm⁻³ they lose length, and at 0.25 mol dm⁻³ there is no change in length.
What is the water potential relationship between the 0.25 mol dm⁻³ solution and the potato cells?
What is the water potential relationship between the 0.25 mol dm⁻³ solution and the potato cells?
- The solution has a higher water potential than the potato cells.
- The solution has a lower water potential than the potato cells.
- The solution and the potato cells have equal water potential.
- The water potential difference is at its maximum.
