Students of Grade 7 conducted an experiment to demonstrate the importance of carbon dioxide in photosynthesis. They placed a leaf in a conical flask containing potassium hydroxide, which absorbed all carbon dioxide. After exposing the setup to sunlight for 6 hours, they tested the leaf with iodine solution, which didn't turn blue-black, indicating the absence of starch. This inference suggests that without carbon dioxide, photosynthesis couldn't occur, as evidenced by the lac… See more
