Neco 2024 Biology Question 47
Practice objective / multiple choice question 47 from the 2024 Neco Biology examination.
During the night a desert shrub experiences a vapor pressure deficit (VPD) of 2 kPa. Its total leaf area is 0.5 m^{2} and stomatal conductance is 0.20 mol m^{-2} s^{-1}. (i) Calculate the rate of water loss in liters per hour. (ii) Three possible adaptations are: (A) halve leaf area, (B) reduce stomatal conductance by 30%, (C) increase leaf thickness reducing effective VPD by 20%. Which adaptation yields the greatest reduction in water loss and what is the percentage reduction relative to the original rate?
