Photosynthetic, oxygen-producing bacteria, some of which are capable of nitrogen-fixation (previously known as "blue-green algae").

Photosynthetic, oxygen-producing microbes.

Single-celled, prokaryotic, microscopic organisms. Before being reclassified as monera, they were called blue-green algae.

blue-green pigmented bacteria

A group of photosynthetic bacteria also known as blue-green algae, produce oxygen in presence of light and fix both carbon dioxide and nitrogen.

see blue-green algae.

Often called blue-green algae; a primitive life form that grows in fresh and seawater and which may contain toxins

Ubiquitous oxygenic photosynthetic prokaryotes that are evolutionarily ancient and that have maintained a significant presence on Earth in essentially all habitats. Previously called blue-green algae.

Photosynthetic moneran autotrophs (bacteria), known as bluegreen algae, but including species of many different colors, living in moist or watered sites exposed to sunlight.

Commonly referred to as "red slime algae" in marine aquaria and "blue-green algae" in freshwater aquaria. Not an algae at all, but a fast-growing bacteria.

the scientific name for the most common variety of blue-green algae found in swimming pools.

Phototrophic bacteria capable of using light energy to extract hydrogen from water, with the production of molecular oxygen : Ancestral to chloroplasts. ~ See Also: Chlorophyll, Chloroplast.

predominantly photosynthetic prokaryotic organisms containing a blue pigment in addition to chlorophyll; occur singly or in colonies in diverse habitats; important as phytoplankton

A type of bacteria living in damp soil or rocks, or fresh or salt water, that performs photosynthesis, a process in which light, energy, water, and carbon dioxide are converted into oxygen and carbohydrates (sugars).

Photosynthetic bacteria with a characteristic blue-green color, commonly known as the blue-green algae

a type of bacteria within genus Synechococcus

a group of unicellular photosynthetic organisms without a well-defined nucleus; sometimes called "blue-green algae" although they are not actually algae

si-an-o-bak-TEAR-ee-ah Unicellular algae that have bluish-green pigments. 64

microscopic plants (bluegreen algae) that photosynthesise but are more closely related to bacteria than to other plants. They often contain blue-green pigments and were probably one of the earliest forms of life on Earth.

a class of bacteria which make use of oxygen producing photosynthesis.

A major grouping within bacteria; produce carbohydrates and oxygen through photosynthesis. Found in freshwater and marine environments and may be solitary or colonial. Used to be referred to as the blue green algae.

photosynthetic bacteria formerly called blue-green algae, their growth forms tend to be filamentous.

Blue-green bacteria; unicellular or filamentous chains of cells that carry out photosynthesis.

the bacteria that can grow photosynthetically via oxygenic photophosphorylation. They are believed to have originated in the Archean time and are responsible for forming stromatolites. They are also thought to be largely responsible for the oxygen in Earth's atmosphere.

Bacteria (sometimes called «blue-green algae») whose photosynthesis liberate oxygen. Cyanobacteria first appeared about 3.5 billion years ago or even earlier. Their activity added oxygen to the atmosphere and created reef-like carbonate buildups (stromatolites) which covered the bottom of the wast shallow basins during the most of the history of life. Cyanobacterial mats could be one of the major sources of the organic matter preserved as the carbon-rich rocks and oil known in the Precambrian.

A group of microorganisms with bacteria-like properties that can cause taste, odour and other problems in water supplies. Also known as blue-green algae.

prokaryotic producers that produced the oxygen that first made Earth inhabitable for other living things

Blue-green single celled algae. Not a desireable addition to an aquarium.

(formerly called blue-green algae) Single-celled organisms that perform a type of photosynthesis.

(sigh - an- o - bak - teer - ee - uh) Blue-green algae; there are over 7,500 species of cyanobacteria and they are found in many environments: damp soil and rocks, fresh water, and salt water.

Organisms that can form large colored mats. They are usually blue-green in color.

Formerly called blue-green algae or cyanophytes.

Bacteria living in lakes and streams that make their own food instead of decomposing dead organisms and are very similar to freshwater algae in lake ecosystems. Many cyanobacteria grow especially well in lakes with high phosphorus content and are sometimes used as indicators of change due to human impacts through watershed development. Several species can make toxins dangerous to humans and other mammals if ingested. High concentrations of these cells in the water can result in closure of lakes to recreation or domestic use of water, although this has been relatively rare in occurrence historically.

blue-green colored bacteria that are capable of photosynthesis

Filamentous or single-celled bacteria that fix carbon and nitrogen (formerly called blue-green algae). Only the filamentous species can be seen without a microscope. Cyanobacterial crusts with low biomass are generally the color of the soil and those with high biomass and diversity are dark (brown to black)

Blue-green algae. One species causes a red tide.

Bacteria that have the ability to photosynthesize.

Type of phototrophic eubacteria [ edit

Single-celled organisms (singular = cyanobacterium) similar to bacteria, except cyanobacteria contain the green pigment chlorophyll (as well as other pigments), which traps the energy of sunlight and enables these organisms to carry on photosynthesis.

A type of photosynthetic eubacteria that possess the ability to phothsynthesize.

Cyanobacteria (Greek: (kyanós) = blue + bacterium) is a phylum (or "division") of Bacteria that obtain their energy through photosynthesis. They are often still referred to as blue-green algae, although they are in fact prokaryotes like bacteria. The description is primarily used to reflect their appearance and ecological role rather than their evolutionary lineage.
