One of the three domains of life, consisting of prokaryotic and unicellular organisms.

A colony type where cells form long thread-like structures, such as those in certain cyanobacteria.

A method to classify bacteria as Gram positive or Gram negative based on cell wall structure.

Barrel-shaped cells that are responsible for growth in filamentous cyanobacteria.

Also known as blue-green algae; gram negative autotrophic bacteria that perform photosynthesis.

Specialized cells in some cyanobacteria for nitrogen fixation; they are larger and round.

A symbiotic relationship where Azolla fern and Anabaena cyanobacteria collaborate for photosynthesis and nitrogen fixation.

A polymer that forms the cell wall of many bacteria, key in distinguishing Gram positive from Gram negative.

Archaea that thrive in extreme environments such as salt flats and hot springs.

Rhizobium bacteria live in the root nodules of clover, fixing nitrogen for the plant.
