Verified step by step guidance1
Understand the process of photosynthesis: Photosynthesis is a chemical reaction that occurs in plants, algae, and some bacteria, allowing them to convert light energy into chemical energy stored in glucose.
Identify the inputs of photosynthesis: The primary inputs are carbon dioxide (CO₂) and water (H₂O). These are absorbed by the plant from the environment.
Recognize the role of light energy: Light energy, usually from the sun, is absorbed by chlorophyll in the plant's leaves, which drives the photosynthesis process.
Determine the outputs of photosynthesis: The process results in the production of glucose (C₆H₁₂O₆) and oxygen (O₂). Glucose is used by the plant for energy and growth, while oxygen is released into the atmosphere.
Summarize the overall chemical equation: The balanced chemical equation for photosynthesis is: 6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂. This equation shows the transformation of carbon dioxide and water into glucose and oxygen, facilitated by light energy.
