A mature tropical tree, 30 m tall, is growing in a region where the soil water is relatively dilute. The following data are recorded: - At the root surface the solute concentration in the xylem sap is 0.01 mol L⁻¹ and the pressure potential is +0.20 MPa. - At the leaf petiole the solute concentration in the xylem sap is 0.05 mol L⁻¹ and the pressure potential is –0.30 MPa (tension). - Temperature is 25 °C. Assume the solute is non‑ionic (i = 1) and use the relation ψs = –i C R T, where R = 0.0831 L bar K⁻¹ mol⁻¹ and 1 bar = 0.10 MPa. Answer the following:
