Introduction Photosynthesis has a very important role in our day-to-day life. Though we may not be able to see the process directly, it fuels the growth of our food and allows for the production of the oxygen we breathe. With this in mind, any improvements discovered pertaining to photosynthesis could be widely used and extremely helpful. Many scientists have conducted experiments in an attempt to discover the exact mechanisms that fuel the process of photosynthesis, adjusting different variables so as to discover the circumstances under which photosynthesis occurs at its optimum potential. Our lab group conducted one such experiment that isolated the variable of light. The first trial utilized white light as the control, and the second trial utilized red light. The initial hypothesis stated that the leaf that was exposed to white light would have a higher photosynthetic rate than the leaf that was exposed to only red light, because white light is a combination of all colored light and red light is simply red. However, after researching other experiments, this hypothesis was somewhat disputed. For example, Muneer et al. (2014) conducted research that suggests certain colors of light may actually be detrimental to the process of photosynthesis (specifically green light, in their experiment). This would mean that white light could possibly decrease the photosynthetic rate, which is contrary to what the initial hypothesis stated.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
