Why Does Blue Have The Highest Rate Of Photosynthesis

The data found in this experiment supported the initial statement in the hypothesis, that blue would have the highest rate of photosynthesis (see Figure 7). The second part of the prediction was refuted by the data, as green had a higher rate than both yellow and red. This result seems to go against the experiment, however the answer is in Figure 5. When adding green food coloring to the solution (see Methods) dilution also took place. When comparing the wavelength of 540 nm (see Tables 1 & 2) with the its corresponding color in Figure 5, the green is almost a turquoise. Since this color is closer to blue, the fastest photosynthesizing wavelength, it answers the question as to why it came before red and yellow (see Figure 7).
From the results, it can be concluded that the level of photosynthesis depends on the level of energy the light carries, and its absorbency. The energy of the light is inversely proportional to the wavelength, so a long wavelength like red carries little energy but a short wavelength like blue carries a lot. But if this is true, then why does red appear as it does in Figure 7 when it carries the least energy? Well, this is because it is highly absorbed, so a lot of the light is taken in, and is not reflected. Whether or not the light is reflected matters far
To ensure accurate results, these other factors were kept constant throughout the lab: temperature, concentration of NaHCO3, technique and apparatus. If the temperature was altered it would affect the rate of enzymes which control the reaction, and will make it faster or slower. Therefore, the concept of varying wavelengths becomes obsolete when it's dependant on several other factors. Also, if the concentration of NaHCO3 increased or decreased, it would affect the rate of photosynthesis, as all plants requires carbon dioxide in one form or another to
