Classification
Domain: Prokaryota
Kingdom: Monera
This kingdom includes complex and diverse bacteria. They lack a
nuclear membrane and go through cell division via binary fission.
Phylum: Cyanobacteria
This phylum includes photoautotrophic bacteria that utilize
photosynthesis but lack chloroplasts. These cells have no flagella.
Class: Cyanophyceae
This class contains unicellular and multicellular algae without a
true nucleus or chromatophore. They have no known sexual
reproduction.
Order: Nostocales
This order is characterized by filamentous bacteria with branching.
Family: Oscillatoriaceae
This family includes un-branched cells that show spiral movement. It
rotatates along its axis. They have no heterocysts.
Genus: Arthrospira
This genus is multicellular and a long cylinder.
Species: Arthrospira platensis
This species is classified as spirally coiled with granulated
cross-walls.
