Do Plants Perform Aerobic Respiration? Procedure: 1. As a table group, set up seed germination and photosynthesis/respiration investigation with bromothymol blue: a. test tube + seed + 10 mL bromothymol blue + check pH b. test tube + 7 cm Elodea + 20 mL bromothymol blue + check pH + tin foil c. test tube + 7 cm Elodea + 20 mL bromothymol blue + check pH + no tin foil d. test tube + 20 mL bromothymol blue + check pH (half the groups wrap this test tube in tin foil) 2. After 72 hours, check your qualitative results (color change) and quantitative results (pH) and write a detailed description of what you observed, both

Use the terms photosynthesis and cellular (aerobic) respiration in your hypotheses. For students who were unable to attend class on the day we analyzed the results, below are the three possible results: 1 2 3 1 – what the bromothymol blue looked like for set-up a . The final pH was 5.8. 2 – what the bromothymol blue looked like for set-up b . The final pH was 6.8. 3 – what the bromothymol blue looked like for set-up c and d . The final pH was 7.5....

    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.
