Neco 2020 Biology Question 36
Practice objective / multiple choice question 36 from the 2020 Neco Biology examination.
Plant X growing in a desert has a leaf surface area of \(150\ \text{cm}^2\). Its stomata open only at night for 4 h, during which it absorbs \(0.8\ \text{mmol\ CO}_2\) per hour. When stomata are open, the transpiration rate is \(0.05\ \text{mmol\ H}_2\text{O}\) per hour per \(\text{cm}^2\). The plant loses a total of \(12\ \text{mmol\ H}_2\text{O}\) in 24 h. Based on these data, which photosynthetic adaptation does Plant X most likely exhibit?
