Photosynthetic cells are quite diverse and include cells found in green plants, phytoplankton, and cyanobacteria. During the process of photosynthesis, cells use carbon dioxide and energy from the ...

when photosynthetic cyanobacteria lived symbiotically within other primitive cellular organisms. “To our knowledge, this is the first time that photosynthetic electron transport has been ...

As early as 3 billion years ago, cyanobacteria, which are capable of photosynthesis, started growing. It is thought that these bacteria evolved because of photosynthesis. The Earth was 5 billion years ...

indicate photosynthesis has been around for even longer than that. It is widely believed that cyanobacteria drove the accumulation of oxygen in Earth’s atmosphere 2.4 billion years ago.

Scientists say they have discovered the oldest evidence of photosynthesis ... Scientists believe cyanobacteria is responsible for so much oxygen developing in Earth's atmosphere millions of ...

A turning point came about 3.4 to 2.9 billion years ago when tiny life forms called cyanobacteria evolved a process called oxygenic photosynthesis ... accumulate in the atmosphere and oceans.

Professor Brian Cox explains how the Earth developed an oxygen rich atmosphere. The secret lies with an ancient group of organisms called cyanobacteria ... own food using photosynthetic pigments.

This process, called photosynthesis, is fundamental to almost all life on Earth. Primary producers (plants, most familiarly, but also algae and cyanobacteria) use it to make their own food ...
