Question

Yes — under light, the plant removed CO2 (from the water), demonstrated by the BTB changing from yellow back toward blue.
- Does the data support the hypothesis? Yes. The experimental jar with the plant changed color toward blue while the control remained yellow, which supports the idea that the plant was using CO2 (reducing acidity) during photosynthesis.
- Improvements / what to do differently:
- Add a dark control with a plant kept in the dark to separate photosynthesis from respiration (in the dark a plant will not remove CO2 and the solution may stay yellow or become more acidic).
- Use replicates (at least 3 of each condition) for more reliable

can you shorten and make it in a format that the questions dont need to be here and make it one hole paragraph

Answer 1

The data support the hypothesis: the jar with the plant shifted from yellow toward blue while the control stayed yellow, indicating the plant removed CO2 during photosynthesis; to strengthen the experiment, include a dark control (plant kept in the dark to separate photosynthesis from respiration) and use at least three replicates per condition for more reliable results.
