Photosynthesis allows plants, algae and certain bacteria to turn sunlight into chemical energy. The amazing feat is achieved because sunlight can fuel a reaction between water and carbon dioxide that, in turn, produces carbohydrates (simple sugars) and oxygen. Here is the latest news on photosynthesis, including the oldest evidence of it on Earth and how blocking photosynthesis on a large scale can affect food chains.

Watch the world choke on CO2 in eerie NASA videos of manmade emissions
The animations highlight emissions from different human and natural sources, with the main contribution coming from the burning of fossil fuels.
Scientists have finally discovered how photosynthesis starts — by setting it off with a single photon
For the first time, researchers have observed how just one particle of light can trigger photosynthesis in bacteria — finally revealing the first step of the crucial process.
