BTB is a chemical indicator. It changes color to indicate the amount of carbon dioxide present in the test tubes (more blue = less CO2, more yellow = more CO2). An aquatic plant was placed in each test tube. The test tube on the left was placed in the dark and the one on the right was in the light. Which of the following best explains the results?
The solution in the right test tube became more blue because the algae was doing more photosynthesis and absorbing carbon dioxide.
The solution in the right test tube became more blue because the algae was doing more photosynthesis and producing carbon dioxide.
The solution in the right test tube became more blue because the algae was only doing cellular respiration and producing carbon dioxide.
The solution in the right test tube became more yellow because the algae was only doing cellular respiration and absorbing carbon dioxide.
