The document describes the Kingdom Monera, which consists mainly of eubacteria and cyanobacteria. Eubacteria are heterotrophic organisms that are named according to their shape, such as coccus (round), spirillum (spiral), and bacillus (rod-shaped). Cyanobacteria are autotrophic organisms commonly found in aquatic and terrestrial environments; they can exist as unicellular, colonial, or filamentous forms, and some can fix nitrogen through specialized cells called heterocysts.

1. KINGDOM MONERA

2.  Consist mainly of eubacteria
and blue-green algae or
cyanobacteria
 They tend to live together in
clumps, chains or planes

3. EUBACTERIA
 They are heterotropic organisms
 They are named according to their
shape

4. EUBACTERIA
1. COCCUS
- round or sperical
2. SPIRILLUM
- spiral or helical shape
3. BACILLUS
- rod-shape

5. COCCUS

6. SPIRILLUM

7. BACCILUS

8. STAPHYLOCOCCI
 Form irregular
clusters of sperical
cells

9. STREPTOCOCCI
 Form a long chain

10. 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

11. 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
