What is the other name of Cyanobacteria?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
Cyanobacteria are commonly called blue-green algae due to their characteristic blue-green coloration from photosynthetic pigments. However, this common name is scientifically misleading because cyanobacteria are prokaryotic bacteria, not true algae (which are eukaryotic). Other names include:
- Cyanophyta (in older classification systems)
- Blue-green bacteria
These photosynthetic microorganisms contain chlorophyll-a and phycobilin pigments (phycocyanin for blue color and phycoerythrin for red). They're among Earth's oldest life forms, responsible for oxygenating the early atmosphere and forming stromatolites. Common examples include Nostoc, Anabaena, and Spirulina.
