The document summarizes the Kingdom Monera, which consists of eubacteria and cyanobacteria. Eubacteria are heterotrophic organisms named according to their shape as coccus (round), spirillum (spiral), or bacillus (rod-shaped). Cyanobacteria are autotrophic organisms commonly found in water and land, 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
