Glucose is made through a process called photosynthesis. The equation for photosynthesis is:

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

Here's what each part of the equation represents:

* 6CO₂: Six molecules of carbon dioxide (CO₂)

* 6H₂O: Six molecules of water (H₂O)

* light energy: Light energy from the sun

* C₆H₁₂O₆: One molecule of glucose (C₆H₁₂O₆)

* 6O₂: Six molecules of oxygen (O₂)

In simpler terms:

Plants take in carbon dioxide from the air and water from the soil. They use light energy from the sun to convert these ingredients into glucose (a type of sugar) and oxygen. The glucose is used as food for the plant, and the oxygen is released into the atmosphere.
