Reference Photosynthesis is the process used by plants, algae and certain bacteria to turn sunlight, carbon dioxide and water into food (sugars) and oxygen.
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.
By grafting their roots together in a hidden underground network, trees could be forming giant "superorganisms" that span entire forests.
A paper published in 2017 appeared to show a limited quantum effect in bacteria. Now scientists argue that something much weirder happened.
The dinosaur-killing asteroid that collided with Earth about 65.5 million years ago plunged the planet into a darkness that lasted nearly two years, a new study finds.
Humans can be vegetarians, choosing to forgo meat, but what about trees? After all, trees need only soil, sunlight and water to survive, right?
Carbon dioxide emissions are fueling more verdant landscapes around the globe, but the potentially temporary greening doesn't mean global warming is good.
Cyanobacteria may use their whole body as a light-gathering apparatus, similar to a camera that helps the primitive organisms "see" and move toward light.
It is a mystery why oxygen didn't suffuse the Earth's atmosphere until much after the earliest lifeforms that make oxygen arose. Now, new research suggests a reason for the delay.
The Arctic's shrinking sea ice is reshaping the region's food web from the bottom up, a new study reports.
Gobs of microscopic organisms called algae may have met their match in viruses that can invade their cells, ultimately leading to death, new research suggests.
