Here's the breakdown:

* Photosynthesis equation: 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

* CO₂ is carbon dioxide, which is taken in by the plant.

* H₂O is water, which is also taken in by the plant.

* C₆H₁₂O₆ is glucose, a type of sugar that is the plant's food.

* O₂ is oxygen, which is released as a byproduct.

During the light-dependent reactions of photosynthesis, water molecules are split apart, releasing electrons and hydrogen ions. The electrons are used to power the production of ATP (energy) and NADPH (a reducing agent), while the oxygen atoms are combined to form oxygen gas (O₂), which is released into the atmosphere.
