Photosynthesis And Cellular Respiration
Analysis:
My hypothesis was incorrect, as this data refutes it. Photosynthesis and cellular respiration were occurring in this freshwater autotroph. We know this because the test tube places in the light stayed at pH 7.5 and the test tube placed in the dark became 1.5 pH more acidic (7.5 pH to 6 pH). This happened because the test tube in the light had both photosynthesis and cellular respiration occurring and they canceled each other out. There was no extra output of CO2, so the BTB in the test tube in the light remained blue. The test tube in the dark became more acidic. This happened because there was no sunlight so no photosynthesis could occur and cancel out the cellular respiration that was still going on. This process continued outputting
