2. Cyanobacteria - Wikipedia

   en.wikipedia.org/wiki/Cyanobacteria

   Cyanobacteria (/ s aɪ ˌ æ n oʊ b æ k ˈ t ɪər i. ə /), also called Cyanobacteriota or Cyanophyta, are a phylum of autotrophic gram-negative bacteria [4] that can obtain biological energy via oxygenic photosynthesis. The name "cyanobacteria" (from Ancient Greek κύανος (kúanos) 'blue') refers to their bluish green color, [5] [6 ...

3. Photoautotroph - Wikipedia

   en.wikipedia.org/wiki/Photoautotroph

   Cyanobacteria is the only prokaryotic group that performs oxygenic photosynthesis. Anoxygenic photosynthetic bacteria use PSI- and PSII-like photosystems, which are pigment protein complexes for capturing light. [5] Both of these photosystems use bacteriochlorophyll. There are multiple hypotheses for how oxygenic photosynthesis evolved.

4. Synechocystis sp. PCC 6803 - Wikipedia

   en.wikipedia.org/wiki/Synechocystis_sp._PCC_6803

   Synechocystis sp. PCC6803 is a strain of unicellular, freshwater cyanobacteria. Synechocystis sp. PCC6803 is capable of both phototrophic growth by oxygenic photosynthesis during light periods and heterotrophic growth by glycolysis and oxidative phosphorylation during dark periods. [2]

5. Photosynthesis - Wikipedia

   en.wikipedia.org/wiki/Photosynthesis

   Photosynthesis (/ ˌ f oʊ t ə ˈ s ɪ n θ ə s ɪ s / FOH-tə-SINTH-ə-sis) [1] is a system of biological processes by which photosynthetic organisms, such as most plants, algae, and cyanobacteria, convert light energy, typically from sunlight, into the chemical energy necessary to fuel their metabolism.

6. Cyanobacterial morphology - Wikipedia

   en.wikipedia.org/wiki/Cyanobacterial_morphology

   Cyanobacteria are a large and diverse phylum of bacteria defined by their unique combination of pigments and their ability to perform oxygenic photosynthesis. [ 2 ] [ 3 ] Cyanobacteria often live in colonial aggregates that can take a multitude of forms. [ 3 ]

7. Photosystem - Wikipedia

   en.wikipedia.org/wiki/Photosystem

   Oxygenic photosynthesis can be performed by plants and cyanobacteria; cyanobacteria are believed to be the progenitors of the photosystem-containing chloroplasts of eukaryotes. Photosynthetic bacteria that cannot produce oxygen have only one photosystem, which is similar to either PSI or PSII .

8. Light-dependent reactions - Wikipedia

   en.wikipedia.org/wiki/Light-dependent_reactions

   The electron transport chain of photosynthesis is often put in a diagram called the Z-scheme, because the redox diagram from P680 to P700 resembles the letter Z. [3] The final product of PSII is plastoquinol, a mobile electron carrier in the membrane. Plastoquinol transfers the electron from PSII to the proton pump, cytochrome b6f. The ultimate ...

9. Thylakoid - Wikipedia

   en.wikipedia.org/wiki/Thylakoid

   Cyanobacteria are photosynthetic prokaryotes with highly differentiated membrane systems. Cyanobacteria have an internal system of thylakoid membranes where the fully functional electron transfer chains of photosynthesis and respiration reside. The presence of different membrane systems lends these cells a unique complexity among bacteria ...
