Igcse Model Questions Vol1 2019 Biology Question 31
Practice objective / multiple choice question 31 from the 2019 Igcse Model Questions Vol1 Biology examination.
A typical desert plant leaf has an area of \(100\ \text{cm}^2\) and a stomatal density of \(200\) stomata per \(\text{mm}^2\). Each open stomata loses \(0.05\ \mu\text{L}\) of water per hour. A related desert species reduces its leaf area by \(30\%\) and its stomatal density by \(60\%\). Assuming the same water loss per stomata, calculate the percentage reduction in total water loss per hour of the adapted leaf compared with the typical leaf.
