The Effect of Pollution on the Photosynthetic Rate of Spartina alterniflora Mallory Zaccone Katelyn Robinson Hunter Downs Robert Murray Biology 101, College of Charleston, Team Patagonia Abstract: Pollution is often shown to have an effect on plants that grow within city limits. This study investigated the effect of pollution on the photosynthetic rate of Spartina alterniflora (marsh grass) both within the city of Charleston as well as in its rural areas. LoggerPro Software was used to record the amount of CO2 released by each sample. The results of the CO2 were recorded by the students and then used to make a paired two sample for means t-test. There is no significant relationship between pollution and the photosynthetic rate of urban vs. rural marsh grasses. This suggests that the city of Charleston may not be heavily polluted. Introduction: The purpose of this investigation is to determine the difference of photosynthetic rates of urban and rural Spartina alterniflora (marsh grass). Pollution from the city, or urban areas, might have an effect on the photosynthetic rate of the urban marsh grass; therefore it might be different than the photosynthetic rate of the rural marsh grass. For many years now biologist have wondered if city pollution has had an effect on plants and grass, and this experiment will help them with this problem. This

    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.
