Question

Two investigations are needed to show gas exchange during photosynthesis to ensure the reliability and accuracy of the results. The first investigation can measure the uptake of carbon dioxide or the release of oxygen, demonstrating the gas exchange process in a controlled setting. The second investigation, possibly conducted under different conditions or using different methods, can serve as a validation of the first by confirming the results and addressing any potential variables or environmental influences. Together, these investigations provide a more comprehensive understanding of the gas exchange dynamics in photosynthesis, enhancing the overall findings.

Answer 1

To really understand how plants take in carbon dioxide and release oxygen during photosynthesis, two experiments are important. The first experiment checks how much carbon dioxide the plants use or how much oxygen they produce. This helps us see how gas exchange happens in a controlled setting. The second experiment could be done in a different way or under different conditions. This experiment helps confirm the first one by making sure the results are accurate and showing that other factors don't change the outcome. By doing both experiments, we get a better overall picture of how gas exchange works in photosynthesis and can trust the findings more.
