For most of human history, Earth has been known as the “Pale Blue Dot,” a term popularized by astronomer Carl Sagan when ...

Cyanobacteria began contributing oxygen to Earth's mostly noxious atmosphere more than 2 billion years ago. The photosystem ...

Earth's oceans may have been green for billions of years until the first photosynthetic organisms flooded our atmosphere with ...

Cells get nutrients from their environment, but where do those nutrients come from? Virtually all organic material on Earth has been produced by cells that convert energy from the Sun into energy ...

However, the chloroplasts survived and performed photosynthetic processes for at least two days, potentially paving the way for advances in tissue engineering. “As far as we know, this is the ...

Bacteria could be the answer to living solar panels that harness the power of the sun for homes in the future. Here's how they'd work.

Scientists have found that an increase in water salinity in the cells of the marine diatom Nitzschia weakens the connections ...

Some orchids stop making food and feed on fungi instead. Researchers found they do this only when conditions allow.

But for every rule there is an exception. Some plants are non-photosynthetic and parasitic, obtaining their food through a host. All parasitic plants have special organs called haustoria that ...

Researchers try to decode the quantum mechanics of chlorophyll, Nature’s near-perfect light harvester, to harness solar energy flawlessly.

Photosynthesis -- mainly carried out by plants -- is based on a remarkably efficient energy conversion process. To generate chemical energy, sunlight must first be captured and transported further.
