Neco Model Questions Vol1 2017 Biology Question 44
Practice objective / multiple choice question 44 from the 2017 Neco Model Questions Vol1 Biology examination.
In a plant, leaf temperature is 30 °C (saturation vapour pressure = 4.24 kPa) while ambient air temperature is 20 °C (saturation vapour pressure = 2.34 kPa) and the actual vapour pressure of the air is 1.5 kPa. The stomatal conductance is 0.20 mol m⁻² s⁻¹ and the leaf area is 0.05 m². Using the relation \(E = g_s \times VPD \times A\), where \(VPD\) is the vapour‑pressure deficit, calculate the transpiration rate in mol min⁻¹.
