1. Identify the main components involved in photosynthesis: chloroplasts, sunlight, water (H₂O), carbon dioxide (CO₂), glucose (C₆H₁₂O₆), and oxygen (O₂).
2. Recognize that photosynthesis occurs in two main stages: the light-dependent reactions and the Calvin cycle (light-independent reactions).
3. In the light-dependent reactions, sunlight is absorbed by chlorophyll in the thylakoid membranes of the chloroplasts, splitting water into oxygen, protons, and electrons.
4. The energy from sunlight is used to produce ATP and NADPH, which are energy carriers for the next stage.
5. In the Calvin cycle, occurring in the stroma, ATP and NADPH are used to convert CO₂ into glucose through a series of enzyme-driven reactions.
6. Oxygen is released as a byproduct of the light-dependent reactions, while glucose is the primary energy-storing product of the entire process.
7. Summarize the overall chemical equation: 6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂.
Parent Tip: Review the logic above to help your child master the concept of worksheet on photosynthesis.
