3. Kingdom Monera
As we know, there are
different types of organisms
living on this planet
Our first exploration of the 5
Kingdoms will be with
Kingdom Monera
Monerans are quite enormous
in number and highly
diversified in their character
4. Kingdom Monera
When you think of Bacteria – what
comes to mind?
Can you tell me what a Pathogen is?
Pathogen = an organism that causes
disease
Pathogenic bacterium is a bacterium
that causes disease
Are all bacteria bad?
What about cheese, beer, wine?
5. Oldest and most abundant
organisms
Prokaryotic “before a nucleus”
Unicellular & Microscopic
Undergo asexual reproduction
Prokaryotes are single-celled
organisms. They are the
smallest, simplest organisms
6. There are two subkingdoms of Kingdom
Monera:
Archaebacteria-can live in the most
extreme of environments.
7. Is also called the true bacteria
Not classified according to shape
but according to chemical
composition of their cell walls
and reaction to Gram stain
8. These bacteria live in very hot, acid habitats of 60-80
and pH 2-4, like the photo of a "Hot springs" below, the
red stain on the rocks are the prokaryotic cells.
9. Eubacteria are more
modern bacteria.
Inhabit nearly
every known
habitat
Consumers,
producers, and
decomposers
Some cause
disease but most
are harmless
10. They are found
in nearly every
habitat studied,
including some
that no other
organism is able
to withstand.
11. Bacteria have a cell wall, a
cell membrane surrounds
the cell but no membrane-
bound organelles such as a
nucleus, mitochondria,
chloroplasts, Golgi
apparatus, or ER. Some are
covered by a layer of
“slime” called a capsule.
Some have flagella for
locomotion.

13. 1. Cocci – spherical
(coccus)
2. Bacilli – rod-shaped
(bacillus)
3. Spirilla – spiral
(spirillum)
Next week – we will be
looking for these under
the microscope in
Experiment 2.2
14.
15. Most are heterotrophs although some are
autotrophs.
