Definition
Photosynthesis is the process by which plants make food using sunlight, CO₂, and water.
Equation
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
Stages
• Light Reaction (ATP, NADPH, O₂)
• Dark Reaction / Calvin Cycle (Glucose formation)
Location
Occurs in chloroplasts of plant cells.
Key Points
• Chlorophyll absorbs sunlight
• CO₂ is used in dark reaction
• Oxygen is released
Factors Affecting
• Light intensity
• Carbon dioxide
• Temperature
