The purpose of these two investigations was to show gas exchange during photosynthesis. In 3-5 sentences explain why two investigations are needed to show gas exchange during photosynthesis?(4 points)

Answer 1

Two investigations are needed to demonstrate gas exchange during photosynthesis because they can address different aspects of the process and validate findings through comparison. The first investigation may focus on measuring oxygen production, as oxygen is released as a byproduct of photosynthesis, while the second could emphasize carbon dioxide uptake, indicating how plants take in CO2 for photosynthesis. Together, these complementary measurements reinforce the understanding of photosynthetic gas exchange dynamics, allowing for a more comprehensive analysis of both inputs and outputs involved in the process. Additionally, using two different methods can help identify any discrepancies and strengthen the overall conclusions drawn from the experiments.
