Waec Model Questions Vol1 2022 Biology Question 38
Practice objective / multiple choice question 38 from the 2022 Waec Model Questions Vol1 Biology examination.
A desert plant originally has a stomatal density of 300 stomata mm⁻² and a cuticle thickness of 5 µm. Its transpiration rate is 12 mg H₂O·h⁻¹·cm⁻² and is directly proportional to stomatal density and inversely proportional to cuticle thickness. After adaptation, the stomatal density falls to 150 stomata mm⁻² and the cuticle thickness increases to 15 µm. What is the new transpiration rate (in mg H₂O·h⁻¹·cm⁻²)?
