* Glucose (C6H12O6): This is a simple sugar that serves as the primary energy source for plants and other organisms.

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

The equation for photosynthesis summarizes this:

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).
