This learning resource explores the process of plant respiration and how energy is conserved as plants break down glucose. It uses the Peperomia plant as an example, explaining the role of glucose (C₆H₁₂O₆) in energy storage and how oxygen (O₂) is utilized in respiration, resulting in the production of carbon dioxide (CO₂) and water (H₂O). The document emphasizes that atoms are conserved during these chemical changes, highlighting the importance of the Law of Conservation of Matter. The resource includes an investigation designed for students to compare the atoms in glucose before and after the change, reinforcing their understanding of matter conservation in biological processes.
