The effects of water contaminated by vegetable oil on the plant Elodea’s ability tophotosynthesizeJoann LouisBiology 1441; Instructor Patricia Dailey; October 9th, 2012Oil spills are a catastrophe that have a detrimental effect on aquatic life, specifically its vegetation. The effects often have a long-lasting effect on plant life and its photosynthesis ability,and maintaining aquatic life healthy and viable is important so that the equilibrium amongst other environments is steady. In order to test this bond, two Elodea samples are kept in either a water or an oil-water solution, and once an hour has passed, the water is tested for CO2 levels. The control of water is used and a comparison is made. The control water sample and the oil-water sample have essentially nothing of a varied amount of CO2, while the Elodeasample with water had caused a slight decrease in the levels. It can be concluded that the oil did have a negative effect on the Elodea’s photosynthesis function, and that with time it would cause worse consequences for the plant. The experiment can be applied to the real-life situations of oil spills across the globe, showing that oil does have an effect, and that with time oil-contaminated water could hurt the aquatic plant life. With the longer exposure the vegetation has of oil spills, the worse off the plants will be.Introduction Life in aquatic environments is incredibly important to the world. Underwater plants provide for oxygen and shelter for the creatures and fish people have grown dependent on for a main food source. It is vitally crucial to help maintain a healthy aquatic atmosphere in order to keep a homeostasis between the other worldly environments, and yet one of the problematic issues that hurt aquatic life is at the fault of human activity – oil spills. When oil spills occur in a vast 1

variety of water collections across the globe, such as seas, oceans, rivers, etc., the effects are quite detrimental to not only the aquatic creatures, but also the vegetation. Oil does not mix with water, and the concoction that is produced has the oil on top, as theliquid is less dense than water. The oily film makes it harder for sunlight to reach the plants beneath the surface, and with less if any sunlight filtering through, the plants’ photosynthesize process is deterred greatly. The pace of the function would decrease, and in result, the plants would not be producing the essential nutrients and oxygen it needs to give off to keep the environment and itself going. As Lee and Lin (2013) see are issues, in gulf areas that oil spills

    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.
