Neco Model Questions Vol1 2022 Biology Question 4
Practice objective / multiple choice question 4 from the 2022 Neco Model Questions Vol1 Biology examination.
Plant A and Plant B are desert shrubs. Plant A has a leaf area of \(0.8\ \text{m}^{2}\) and a stomatal density of \(200\) stomata mm\(^{-2}\). Each stomata of Plant A contributes a conductance of \(0.05\ \text{mol\,s}^{-1}\). Plant B has a leaf area of \(0.5\ \text{m}^{2}\) and a stomatal density of \(300\) stomata mm\(^{-2}\), each contributing \(0.03\ \text{mol\,s}^{-1}\). Assuming total water‑loss rate is proportional to the product (leaf area × stomatal density × conductance per stomata), determine which plant loses water faster and calculate the factor by which its loss exceeds the other.
