Practice objective / multiple choice question 7 from the 2021 Neco Biology examination.
A leaf of area \(150\ \text{cm}^2\) loses water by transpiration at a rate of \(0.5\ \text{mg\,cm}^{-2}\,\text{h}^{-1}\) for 8 h during the day. Simultaneously, the root system of total area \(120\ \text{cm}^2\) absorbs water by root pressure at \(0.3\ \text{mg\,cm}^{-2}\,\text{h}^{-1}\) for the same period. Calculate the net water loss of the plant over the day in grams.
