Indeed, chloroplasts resemble modern cyanobacteria ... Chloroplasts also have a third internal membrane called the thylakoid membrane, which is extensively folded and appears as stacks of ...

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

Both PSI and PSII are multisubunit pigment protein complexes embedded in the thylakoid membrane of plants, algae and cyanobacteria. They carry out unique redox chemistry. On absorbing light ...

It found 30 sequences associated with biological processes (typically carbohydrate transport), 35 with cellular components (usually mapped to the plasma membrane-derived thylakoid membrane), and ...
