The basics of photosynthesis

Photosynthesis is a chemical reaction through which plants absorb light and transform it into sugars and oxygen. It is a highly complex process that is vital to nearly all organisms on Earth. But exactly how does it work?

Plants are autotrophic organisms, which means that plants produce their own food and they support other organisms. Without the sun, photosynthesis would stop and no life could be sustained.

Photosynthesis is the chemical reaction where carbon dioxide (CO2) and water form sugars and oxygen in the presence of light energy. The sugars formed by photosynthesis are used by the plants as a food energy source. Under natural conditions, the sun provides the energy to trigger photosynthesis.

Plants use a specific portion of the solar (light) spectrum for photosynthesis, which is called Photosynthetic Active Radiation (PAR). PAR is the region of the solar radiation between 400 and 700 nm.
