[{"title": "Photosynthesis Equation", "content": "6CO₂ + 6H₂O + sunlight → C₆H₁₂O₆ + 6O₂. Reactants: carbon dioxide and water. Products: glucose and oxygen. Energy source: sunlight.", "solution": "Plants take in CO₂ and water, use sunlight, and produce sugar and oxygen."}, {"title": "Plant Life Cycle", "content": "A bean seed is planted in soil → it absorbs water and germinates → a root grows down, a shoot grows up → leaves develop and photosynthesis begins → the plant flowers → bees pollinate the flowers → new bean pods (seeds) form.", "solution": "Seed → Germination → Growth → Flowering → Pollination → Seed Production"}]
