- Why do plants need to use cellular respiration if they can do photosynthesis?
- If a plant is in the dark for 24 hours, what will happen to its mass: will it increase, decrease, or stay the same? Explain your answer.
- Explain how the action of your respiratory system relates to the process of cellular respiration.
- Which stage of cellular respiration produces the most energy?
- How much energy is produced during fermentation? Why do some organisms undergo fermentation instead of respiration?
- What factors influenced fermentation the most in your class experiment? Develop a hypothesis for why this might be.
- Both glucose and ATP store chemical energy. Why can’t glucose be used to directly power cells instead of ATP?
- All experiments should have controls, if possible. Explain what a positive control and a negative control can tell you about your experiment.
