Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy, resulting in the synthesis of organic compounds.

Here's a breakdown:

• Inputs: Photosynthesis uses carbon dioxide (CO₂) from the air and water (H₂O), along with sunlight.
• Process: Chlorophyll, a pigment in chloroplasts, absorbs sunlight. This light energy drives a series of chemical reactions. Water is oxidized, meaning it loses electrons, and carbon dioxide is reduced, meaning it gains electrons.
• Outputs: Glucose (a sugar, C₆H₁₂O₆) is produced, which the plant uses as food. Oxygen (O₂) is released as a byproduct.

The overall chemical equation is:

6CO₂ + 6H₂O + Light Energy → C₆H₁₂O₆ + 6O₂

In simple terms, plants use sunlight to turn carbon dioxide and water into food (glucose) and release oxygen. This process is vital for life on Earth, as it produces the oxygen we breathe and forms the base of most food chains.
