In the experiment that you performed, why did Tube 1 change color when placed in the dark?
Understand the Problem
The question is asking for an explanation of why a specific test tube changed color when placed in the dark, relating to the processes of photosynthesis and cellular respiration in plants.
Answer
The plant was performing cellular respiration, releasing carbon dioxide.
The plant was performing cellular respiration, releasing carbon dioxide.
Answer for screen readers
The plant was performing cellular respiration, releasing carbon dioxide.
More Information
In the absence of light, photosynthesis stops and only cellular respiration occurs. This process releases carbon dioxide, which can change the pH and color of the solution.
Tips
A common mistake is assuming photosynthesis occurs without light. Remember, photosynthesis requires light, so in the dark, only respiration takes place.
