What is Anabaena classified as?

What is the kingdom of Anabaena azollae?

Bacteria are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats.

Where is Anabaena azollae found?

Asia; a blue-green algae (Anabaena azollae) is always found in pockets on the leaves of Azolla and helps convert nitrogen to a form usable by other plants (see nitrogen-fixation), thus greatly increasing the productivity of rice paddies where the fern occurs.

What are the characteristics of Anabaena?

Anabaena has uniseriate, straight, curved, or coiled trichomes that may be constricted at the cell walls. The blue-green to yellow-green colored cells may be spherical, ellipsoidal, cylindrical, or bent, but overall look much like a string of beads. Some species have soft and colorless mucilage.

Is Anabaena a fungi?

Anabaena is a filamentous true cyanobacterium that has nitrogen-fixing capabilities. It is a member of kingdom Monera. So, the correct answer is ‘Monera’.

What is the importance of Anabaena?

Anabaena azalea plays a significant role in farming where it is used as a biofertilizer and soil stabilizer. Anabaena azallea is a symbiotically related photoautotrophic cyanobacterium with the tiny eukaryotic water fern Azolla pinnata, in specialized leaf cavities of the fern under natural conditions.

Is Anabaena free living or symbiotic?

Anabaena is a free living nitrogen fixing cyanobacterium which can form symbiotic association with water fern Azolla.

Is Anabaena a nitrogen-fixing bacteria?

Anabaena, genus of nitrogen-fixing blue-green algae with beadlike or barrel-like cells and interspersed enlarged spores (heterocysts), found as plankton in shallow water and on moist soil. There are both solitary and colonial forms, the latter resembling a closely related genus, Nostoc.

Is Anabaena a protist?

Anabaena is a genus of filamentous cyanobacteria that exist as plankton. They are known for nitrogen-fixing abilities, and they form symbiotic relationships with certain plants, such as the mosquito fern.
Genus:Anabaena Bory de Saint-Vincent ex Bornet & Flahault, 1886

Is Anabaena free living or symbiotic?

Anabaena is a free living nitrogen fixing cyanobacterium which can form symbiotic association with water fern Azolla.

Is Anabaena prokaryotic or eukaryotic?

prokaryotic cells
Anabaena are a genus of Blue-green Algae or Cyanobacteria. Specifically, Anabaena are known for their nitrogen-fixing abilities. These prokaryotic cells are not true algae (which are eukaryotic) but also aren’t truly bacterial cells as they produce energy via photosynthesis.

Is Zygnema a cyanobacteria?

Zygnema is a genus of freshwater filamentous thalloid alga comprising about 100 species. A terrestrial species, Z. terrestre, is known from India. Zygnema grows as a free-floating mass of filaments, although young plants may be found anchored to streambeds with a holdfast.
Genus:Zygnema C. Agardh, 1817

Is Anabaena free living nitrogen fixer?

Solution : Anabaena is a free-living nitrogen fixing cyanobacterium which can form symbiotic association with water fern Azolla.

What are examples of free living organisms?

Fungi contribute extensively to a wide range of ecosystem processes, including decomposition of organic carbon, deposition of recalcitrant carbon, and transformations of nitrogen and phosphorus.

Is Anabaena aerobic or anaerobic?

– Rhodospirillum is a free-living nitrogen-fixing anaerobic bacteria. – Anabaena & Nostoc are symbiotic nitrogen-fixing cyanobacteria. – Rhizobium is symbiotic nitrogen-fixing aerobic bacteria but fixes nitrogen in anaerobic conditions. Note: The nitrogen fixation process is affected by enzymes called nitrogenases.

Which is free living nitrogen-fixing bacteria?

Free-living nitrogen-fixers include the cyanobacteria Anabaena and Nostoc and genera such as Azotobacter, Beijerinckia, and Clostridium.

What is symbiotic nitrogen-fixing bacteria?

Legumes are able to form a symbiotic relationship with nitrogen-fixing soil bacteria called rhizobia. The result of this symbiosis is to form nodules on the plant root, within which the bacteria can convert atmospheric nitrogen into ammonia that can be used by the plant.
