Blue-green algae, also known as Cyanobacteria, are a group of photosynthetic bacteria that many people refer to as "pond scum." Blue-green algae are most often blue-green in color, but can also be blue, green, reddish-purple, or brown. Blue-green algae generally grow in lakes, ponds, and slow-moving streams when the water is warm and enriched with nutrients like phosphorus or nitrogen.
When environmental conditions are just right, blue-green algae can grow very quickly in number. Most species are buoyant and will float to the surface, where they form scum layers or floating mats. When this happens, we call this a "blue-green algae bloom." In Wisconsin, blue-green algae blooms generally occur between mid-June and late September, although in rare instances, blooms have been observed in winter, even under the ice.
Many different species of blue-green algae occur in Wisconsin waters, but the most commonly detected include Anabaena sp., Aphanizomenon sp., Microcystis sp., and Planktothrix sp. It is not always the same species that blooms in a given waterbody, and the dominant species present can change over the course of the season.
How do blue-green algae differ from true algae?Blue-green algae, like true algae, make up a portion of the phytoplankton in many water bodies. However, blue-green algae are generally not eaten by other aquatic organisms, and thus are not an important part of the food chain. True algae (e.g., green algae) are very important to the food chain. They are known as "primary producers", a name given to living organisms that can convert sunlight and inorganic chemicals into usable energy for other living organisms. Most algae are microscopic and serve as the main supply of "high energy" food for larger organisms like zooplankton, which in turn are eaten by small fish. Small fish are then eaten by larger fish, and both small and large fish are eaten by mammals, raptors, and people.

i dont know i m a student of class 9 and i m searching for the answer for - diff. b/w spirogyra and blue green alga
Blue-green algae belong to the Kingdom Bacteria, specifically in the phylum Cyanobacteria.
Golgi apparatus is absent in blue green algae because they do not grow where there is no light.
Blue green algae or cynobacteria are photosynthetic.They produce their food themselves.
zygnema and spirogyra are examples of filamentous algae

Blue green algae is toxic so I would take care with it.

blue green algae has been rename to cyanobacteria because scientists thought that blue green algae is too hard to say
Philippine blue green algae by biologist Gregorio T. Velasquez
fungi because it's bacteria and it's blue and green algae.
its that blue green algae niche is providing food for animals
