ADVERTISEMENTS: In this article we will discuss about the classification of algae. Certain environmental conditions in water bodies can intensify algae growth, causing algal blooms. Cyanobacteria, also called blue-green algae, are microscopic organisms found naturally in all types of water. Cyanobacteria were formerly classified as blue-green algae (les algues bleues in French, las algas azules in Spanish) because of their algal-like appearance, their possession of chlorophyll rather than bacteriochloro-phyll, and their photosynthetic production of oxygen by a two-photosystem process as in algae and higher plants.
