In this experiment, Spinacia oleracea leaves were used to observe the different variables that impact the rate of photosynthesis. In this particular experiment, the leaves were observed while submerged in bicarbonate solution versus a water solution. In addition to that, the effects of the leaves being exposed to red light versus blue light was also observed. It was hypothesized that those exposed to bicarbonate and red light would photosynthesize quicker. It was seen that leaf disks that were submerged in bicarbonate solution photosynthesize quicker (Fig. 1). It was also seen that leaf disks exposed to red light photosynthesize the quickest (Fig. 2). Overall, both hypotheses were supported by the data. Thus, it is concluded that leaves placed
