what is cyanobacteria?

Cyanobacteria - The group cyanobacteria includes another successful group of prokaryotes namely blue green algae. They are photoautotrophic prokaryotes occupying a wide range of habitats. They are predominantly aquatic, found mostly in fresh water bodies. Some species occur in m..

The micro-organisms like cyanobacteria (blue-green algae) and photosynthetic bacteria can also fix nitrogen. Some cyanobacteria also act as symbionts and are present in association with lichens; liverwort - Anthoceros; fronds of water fern - Azolla and roots of a gymnosperm - Cy..

Cyanobacteria reproduce mostly by vegetative and asexual methods. Vegetative reproduction occurs by fission or fragmentation or by the formation of hormogonia. Unicellular forms exhibit fission while filamentous multicellular forms exhibit fragmentation. Asexual reproduction occurs by the..

Question: Example of chemosynthetic bacteria are _____________. 1. E. coli 2. sulphur bacteria 3. cyanobacteria 4. nitrobacter Answer: ..

Photoautotrophic organisms synthesize food with the help of light energy of the sun, carbon dioxide and water. The process of synthesis of food in this method is called photosynthesis, which will be dealt later in this chapter. For example: cyanobacteria (blue-green bacteria, prokaryote..

There are two basic types of cells found in living organisms - the prokaryotic cells and the eukaryotic cells. This classification is based on three main features, namely; Organisation of biomembranes Nature of cytoplasmic organelles and Arrangement of the nuclear material The prokaryotic cells do ..

>Nitrogen fixation is primarily by symbiotic bacteria - Rhizobium or by free living cyanobacteria. For nitrogen fixation, a large amount of energy is derived from ATP molecules. The dinitrogen molecule is reduced to ammonia with the help of enzyme nitrogenase. The nitrifying bacteria conv..
