15. (9 pts.) In an experiment a freshmen biology major conducted an experiment to determine which plant
(spinach versus mustard greens) was more efficient in utilizing light for the photochemical reaction of
photosynthesis. The student placed degassed leaf disks into a 0.1% NaHCO3 solution and exposed the
leaf disk to different concentrations of light (measured as µE/m²/s). After a few minutes, the leaf disks
started to float because of O2 production. She measures the time for each leaf disk to float and average
the times. To graph her results, she the calculated the reciprocal mean float time. The data table and
graph are below.
