Neco 2024 Biology Question 12
Practice objective / multiple choice question 12 from the 2024 Neco Biology examination.
A desert cactus has evolved leaf modifications that reduce its leaf surface area to 5% of a typical leaf which measures \(10\) cm\(^2\). The typical leaf has a stomatal density of \(300\) stomata per mm\(^2\), whereas the cactus leaf has a density of \(150\) stomata per mm\(^2\). Assuming transpiration rate is directly proportional to the total number of stomata, calculate the percentage reduction in water loss of the cactus leaf compared with the typical leaf. Give your answer to one decimal place.
