Experiment: To examine cell respiration, two sealed containers were set up: one with germinating seeds, the other with boiled (dead) seeds. CO₂ levels were monitored over 24 hours.Observation: CO₂ increased only in the container with germinating seeds.Question: What does this suggest?
Correct answer: D. Germinating seeds carry out respiration and produce CO₂.
- A. Boiled seeds produce more CO₂ than germinating ones.
- B. All plant material releases CO₂ equally.
- C. Respiration does not occur in seeds.
- D. Germinating seeds carry out respiration and produce CO₂.
Explanation
The correct answer is that germinating seeds carry out respiration and produce CO₂, as evidenced by the increase in CO₂ levels only in the container with germinating seeds. Boiled seeds do not exhibit this behavior, indicating that respiration is a process specific to living, germinating seeds. The other options are incorrect because they do not align with the experimental observation provided.
