Although unsightly, most mats are not known to pose any environmental or human health risks. However, there are some species of Oscillatoria and related forms of filamentous blue-greens, that have been shown to produce toxins.
What is the purpose of Oscillatoria?
Oscillatoria uses photosynthesis to survive and reproduce. Each filament of oscillatoria consists of trichome which is made up of rows of cells. The tip of the trichome oscillates like a pendulum. in reproduction, it takes place by vegetative means only.
What are the characteristics of 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. The hormogonia can grow into a new, longer filament.

Does Oscillatoria fix nitrogen?
Nostoc, Anabaena, and Oscillatoria are nitrogen- fixing algae. … They are capable of fixing atmospheric nitrogen as free-living forms and also in mutual association with the roots of plants. Other than nitrogen cyanobacteria can also fix carbon from carbon dioxide during photosynthesis.
Why does Oscillatoria deserve its name?

Is Oscillatoria multicellular or unicellular?
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.
What is the size of Oscillatoria?
Lyngbya (including species moved to Limnoraphis) and Oscillatoria have short, wide, coin-like cells (2-8 μm in length; up to 25 μm in width; for comparison, a strand of spider silk is about 5 μm wide).
Is Oscillatoria a plant?
Oscillatoria is a blue-green alga. It is included in the class o The plant is a haploid gametophyte. It is a simple, unbranched filament ont of Oscillatoria is known as a trichome.
How do I get rid of blue green algae in my pond?
There are different options when it comes to treating a pond that has a blue-green algae bloom, one option is to use copper sulfate to kill the blue-green algae. However, this chemical will also kill green algae that helps keep blue-green algae in check and copper sulfate does not breakdown.
Is Oscillatoria a Biofertilizer?
Thus, Oscillatoria sp. can be introduced as biofertilizer for rice (BR 29) cultivation in the northern region of Bangladesh which is economical too. Effect of different treatments on plant height at different days after transplantation (DAT).
Who discovered Oscillatoria?
Oscillatoria was first introduced at the very beginning of the 19th century by Vaucher (1803), when he described 12 Oscillatoria species and included their drawings, as part of a natural history of freshwater organisms.
How you would tell the difference between Nostoc oscillatoria and Anabaena?
Both nostoc and Anabaena reproduce by fragmentation. The difference between nostoc and Anabaena is that Nostoc has a mucilaginous sheath covering its vegetative cells while it is absence is Anabaena.
What is an Akinetes in biology?
An akinete is an enveloped, thick-walled, non-motile, dormant cell formed by filamentous, heterocyst-forming cyanobacteria under the order Nostocales and Stigonematales. … They also accumulate and store various essential material, both of which allows the akinete to serve as a survival structure for up to many years.
What is the function of the Heterocysts of Anabaena?
Anabaena-Azolla
In return, the heterocysts are able to provide the vegetative cells and the Azolla plant with fixed nitrogen in the form of ammonia which supports growth of both organisms.
Is Oscillatoria used in paddy fields?

Is Oscillatoria a Marine?
Marine oscillatoria (Trichodesmium): explanation for aerobic nitrogen fixation without heterocysts. Science.
Can cells without heterocysts fix nitrogen?
Many, though not all, non-heterocystous cyanobacteria can fix N2. However, very few strains can fix N2 aerobically. Nevertheless, these organisms may make a substantial contribution to the global nitrogen cycle.
Is Gloeocapsa a cyanobacteria?
Gloeocapsa (from the Greek gloia (gelatinous) and the Latin capsa (case) ) is a genus of cyanobacteria. The cells secrete individual gelatinous sheaths which can often be seen as sheaths around recently divided cells within outer sheaths.
Do all cells of Trichome of oscillatoria appear similar?
No, they aren’t dependent on each other; the aggregation of cells can be broken into individual cells without killing the cells.
Are nuclei visible in cyanobacteria?
Cyanobacteria Definition
Cyanobacteria are prokaryotic oxygenic phototrophs that contain a green pigment called chlorophyll and a blue photosynthetic pigment called phycobilins. Prokaryotic means they don’t have a membrane-bound nucleus, mitochondria or other type of membrane-bound organelle (like true algae do).
Does Oscillatoria have flagella?
While flagella and cilia are conspicuous methods of locomotion, one of the subtle ways phytoplankton move is shown by Oscillatoria, which are filamentous cyanobacteria. They slowly glide through their medium without the use of cilia or flagella.
Do Oscillatoria cells have chloroplasts?
