In photosynthesis, energy from sunlight combines with carbon dioxide and water to form glucose (a sugar) and oxygen.

Here's the simplified chemical equation:

6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂

* CO₂ = Carbon dioxide

* H₂O = Water

* light energy = Energy from sunlight

* C₆H₁₂O₆ = Glucose (a sugar)

* O₂ = Oxygen

The glucose is a source of energy for the plant, and the oxygen is released into the atmosphere.
