* Glucose (C6H12O6): A simple sugar that serves as the primary energy source for the plant.

* Oxygen (O2): A byproduct of photosynthesis, released into the atmosphere.

The equation for photosynthesis is:

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

This means that six molecules of carbon dioxide (CO2) and six molecules of water (H2O) react in the presence of light energy to produce one molecule of glucose (C6H12O6) and six molecules of oxygen (O2).
