Waec Model Questions Vol1 2020 Biology Question 1
Practice objective / multiple choice question 1 from the 2020 Waec Model Questions Vol1 Biology examination.
In a plant, the water potential (Ψ) values are: soil Ψ = -0.15 MPa, root xylem Ψ = -0.30 MPa, leaf cell Ψ = -1.20 MPa, and atmospheric Ψ = -1.80 MPa. The hydraulic conductance of the root segment is 0.8 mmol m⁻² s⁻¹ MPa⁻¹ and that of the leaf stomatal pathway is 0.5 mmol m⁻² s⁻¹ MPa⁻¹. Assuming the root and leaf pathways are in series, calculate the net water flux (J, in mmol m⁻² s⁻¹) from soil to leaf.
