What does oscillatoria look like?
Description: Oscillatoria is a filamentous blue-green alga that can be found throughout North Carolina. Its filaments are motile and weave into thin mats that coat sediment and other submerged surfaces. The bright blue and blue-green mats are commonly described as looking like spilled paint.
Is oscillatoria a blue-green algae?
Oscillatoria—a blue–green algae.
What are the characteristics of blue-green algae?
Blue-green algae is a unicellular, prokaryotic (pro= primitive, karyon= nucleus) organism. It does not have a well-defined nucleus. The DNA is not present inside the nucleus (means the DNA is naked) rather it is present in the cytoplasm (not enclosed by the nuclear membrane). DNA has no histone protein.
What color is oscillatoria?
It is commonly found in watering-troughs waters, and is mainly blue-green or brown-green. Oscillatoria is an organism that reproduces by fragmentation. Oscillatoria forms long filaments of cells which can break into fragments called hormogonia.
What type of organism is Oscillatoria?
Oscillatoria, genus of blue-green algae common in freshwater environments, including hot springs.
What is the structure of blue-green algae?
Blue-greens are not true algae. They have no nucleus, the structure that encloses the DNA, and no chloroplast, the structure that encloses the photosynthetic membranes, the structures that are evident in photosynthetic true algae.
What organisms were formerly known as blue-green algae?
Cyanobacteria, formerly known as blue-green algae, are photosynthetic microscopic organisms that are technically bacteria. They were originally called blue-green algae because dense growths often turn the water green, blue-green or brownish-green.
Why is Oscillatoria green?
Oscillatoria princeps is the type species (lectotype) of the cyanobacterial (blue green algal) genus Oscillatoria. The cyanobacterium is dark blue green in colour, due to the presence of the phycobilin pigments phycocyanin and phycoerythrin.
Is Oscillatoria unicellular or multicellular?
Oscillatoria annae include unicellular, colonial and filamentous forms some filamentous cyanophytes form differentiated cells called heterocyst, that are speciallized for hydrogen fixation, and resting or spore cells called aconites.
Is Oscillatoria a Marine?
Marine oscillatoria (Trichodesmium): explanation for aerobic nitrogen fixation without heterocysts. Science.
