Our study set out to compare Water Use Efficiency (WUE) levels of Malosma laurina plants in both small and large leaves. We collected a total of 3 data sets, with each set consisting of 5 small leaves and 5 large leaves from a single specimen of Malosma laurina located on Pepperdine’s campus. Parameters including transpiration and photosynthesis were measured to calculate WUE of small and large leaves using an LI- 6400 Gas Exchange System. We hypothesized that small leaves would have a higher WUE rate than large leaves of the M. laurina. Analysis of this data via a paired Student’s t-test showed that our hypothesis was not supported, as our results indicated that the WUE in small leaves was less efficient than that of large leaves.
