Gce Model Questions Vol1 2020 Biology Question 2
Practice objective / multiple choice question 2 from the 2020 Gce Model Questions Vol1 Biology examination.
Two leaf cells, A and B, are at 25 °C. Cell A contains a solute concentration of 0.3 mol L⁻¹ and a pressure potential of +0.2 MPa. Cell B contains 0.1 mol L⁻¹ solute and a pressure potential of -0.1 MPa. Using the equation \(\psi = \psi_s + \psi_p\) where \(\psi_s = -i C R T\) (with \(i = 1\), \(R = 0.008314\) MPa·L·mol⁻¹·K⁻¹ and \(T = 298\) K), determine the direction of water movement and the magnitude of the water‑potential difference between the cells (to two decimal places).
