Igcse Model Questions Vol1 2022 Biology Question 32
Practice objective / multiple choice question 32 from the 2022 Igcse Model Questions Vol1 Biology examination.
In a small plant the root pressure is (0.2\,\text{MPa}\) and the leaf water potential is \(-0.5\,\text{MPa}\). The hydraulic resistance of the xylem is (2\,\text{MPa·h·L}^{-1}\) and that of the leaf is (1\,\text{MPa·h·L}^{-1}\). Using the analogy (\text{flow rate}=\dfrac{\Delta\Psi}{R_{\text{total}}}\), calculate the steady‑state water flow rate in litres per hour, giving your answer to two decimal places.
