Photosynthesis Basics
Think of photosynthesis as nature's way of cooking - plants use sunlight, carbon dioxide, and water to make glucose (sugar) and oxygen. This amazing process happens inside chloroplasts, the tiny green factories in plant cells that capture light energy.
The whole process is endothermic, meaning it absorbs energy from the environment. The simple equation is: carbon dioxide + water → glucose + oxygen (using light energy). You can write this as: 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂.
Once plants make glucose, they're quite clever about what they do with it. Some gets used in respiration to transfer energy for daily activities. The rest gets converted into useful materials like cellulose for strong cell walls, or combined with nitrates to make amino acids for proteins.
Remember: Plants store excess glucose as starch (not glucose itself) because starch is insoluble - cells full of glucose would swell up with water!
