Photosynthesis And Red Light Treatment

Paragraph 1 With a p- value of 0.059229 between our red light treatment and our green light treatment, we fail to reject the null hypothesis and reject our alternative hypothesis because the value was higher than 0.05. Our alternative hypothesis was that red light would be more effective than green light on the rate of photosynthesis and our null hypothesis was that the color of light would not affect the rate of photosynthesis. Without enough evidence to support the alternative hypothesis, we fail to reject the null hypothesis due to a high p-value. Although the p-values when the red light treatment was compared to the white light control treatment our p-value was .004825, giving enough evidence to show that we reject the null hypothesis …show more content…
Depending upon which color the plant absorbs best is determined by its wave length. Being that plants are green in color, they will more than likely benefit from any color other than green. This being because the color an object appears is the color that that object does not absorb. With this in mind, we wanted to test green light against red light, thinking that photosynthesis would react better with red light wavelengths. Although, our thinking was not completely accurate. When comparing red light to white light, the rate of photosynthesis did have a significant change. However, white light was still more effective than either of the light treatments. This is because white light is composed of all colors, giving the photosynthesis to opportunity to absorb more from its specific wavelength that provides for the best rate of photosynthesis. A similar experiment was done with changing the color of light by using plastic covers on the lights. They also concluded that the results were inconclusive due to the minute change for the rate of photosynthesis. They too recommended that the grower could continue to use their original light source, due to inconclusive results …show more content…
One of the bigger uncertainties that we considered was what the wavelength of our light treatments were. Being that we were only using color light bulbs, some of the wavelengths may not be as accurate as it would to actually using a properly colored light source with precise wavelengths. Without out the correct wavelengths, we cannot fully consider our results accurate. This is because we were trying to test to see if the wavelengths would effect the rate of
