KINGDOM MONERA

Consist mainly of eubacteria and blue-green algae or cyanobacteria

They tend to live together in clumps, chains or planes

EUBACTERIA They are heterotropic

organisms

They are named according to their shape

EUBACTERIA1. COCCUS

- round or sperical

2. SPIRILLUM- spiral or helical shape

3. BACILLUS- rod-shape

COCCUS

SPIRILLUM

BACCILUS

STAPHYLOCOCCI

Form irregular clusters of sperical cells

STREPTOCOCCI

Form a long chain

CYANOBACTERIA

They are autotrophic organisms

They are commonly found in fresh water or marine environments and on land

Their cell walls are made up of peptidoglycan, which is poisonous to grazers

CYANOBACTERIA

Can exists as unicellular, colonial or filamentous

Some cyanobacteria can fix nitrogen because of heterocyst, thick walled cells which contain the enzyme nitrogenase used to convert nitrogen gas to ammonia
