Content: The concentration of NaHCO3 was also held constant at 0. 2% for each treatment, along with the volume of NaHCO3 used. pH was maintained at 7. Wavelength of light was uniform at white. All treatments were tested at room temperature. Size of leaf segments and number of leaf segments were also consistent for each treatment. To determine the effect of light intensity on rate of photosynthesis, the leaf mixtures were subjected to intensities of 2200, 4250, 5300, 14400, and 20600 lux. A treatment was performed in the dark (0 lux) for the control. Leaf segments observed floating at 0 lux would indicate oxygen production from spontaneous reactions other than photosynthesis. This would have been subtracted from the rates of photosynthesis of the other treatments to make the correction.
