* Glucose (C6H12O6): This is a simple sugar that serves as the primary energy source for most organisms. Plants store excess glucose as starch.

* Oxygen (O2): This is a byproduct of photosynthesis, released into the atmosphere as a gas.

Here's a simplified equation for photosynthesis:

6CO2 (carbon dioxide) + 6H2O (water) + light energy → C6H12O6 (glucose) + 6O2 (oxygen)

So, in essence, plants use sunlight, water, and carbon dioxide to create glucose and oxygen.
