We knew that photosynthesis was occurring when the leaves began to float. The leaves would float to the top to catch the light so that it could start the process of photosynthesis. 6. Explain how you attempted to reduce error when setting up your experiment or measuring the rate of photosynthesis of your leaf disks. (2) To reduce error, we made sure to measure the correct amount of materials inside of the beakers. We also made sure that all the leaves were degassed before putting them inside of the beaker. The last thing that we did to reduce error was to count each leaf and only put the same amount into each beaker. 7. Did your group or other groups use control(s) in this experiment? Why were those control(s) used? (2 points) Our group did use a control by creating a beaker with only water and no other solution inside of it to see how it would differ between the other beakers that had non water material inside of it.

    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.
