Study Notes
Cyanobacteria Energy Production
- Cyanobacteria obtain energy primarily through photosynthesis, a process that converts light energy into chemical energy.
Origin and Environment
- The origin environment of cyanobacteria is believed to be ancient freshwater or marine habitats, where they played a crucial role in the Earth's oxygenation.
Internal Membranes
- The internal membranes in cyanobacteria are called thylakoids, which are responsible for photosynthesis and energy production.
Evolutionary Relationships
- The proposed name of the paraphyletic and most basal group related to cyanobacteria is Melainabacteria, which is thought to be a sister group to cyanobacteria.
Common Name
- The common name 'blue-green algae' for cyanobacteria is derived from the fact that they have a blue-green pigment called phycocyanin, which gives them their characteristic color.
