Microorganism Types & Differences (MB Quiz 1)

name the 7 types of microorganisms

1. bacteria

2. archaea

3. fungi

4. protozoa

5. algae

6. viruses

7. multicellular animal parasites

This DOMAIN…

• is translated to “before” the nucleus

• lacks a distinct nucleus or organelles

or

• doesn’t contain a nucleus or organelles

prokaryotes

This DOMAIN…

• is translated to “true” nucleus

• has a distinct nucleus and contains organelles

eukaryotes

This DOMAIN/ microorganism type…

• UNIcellular

• are found in EXTREME environments

• LACK PEPTIDOGLYCAN cell walls (or a cell wall completely)

• generally NOT known to CAUSE DISEASE

archaea

This type of microorganism…

• is a PROKARYOTE

• UNIcellular

• contain PEPTIDOGLYCAN cell walls

• divide via BINARY FISSION

• derive nutrition via organic/ inorganic chemicals or photosynthesis

• “swim” using FLAGELLA

bacteria

This type of microorganism …

• is a EUKARYOTE

• contain CHITIN cell walls

• absorb ORGANIC chemicals

• contain YEASTS or MOLDS

fungi

This type of microorganism…

• is a EUKARYOTE

• absorb/ ingest ORGANIC chemicals

• motile via pseudopods, cilia, or flagella

• free-living, parasitic (derive nutrients from living host), or photosynthetic

• reproduce sexually or asexually

protozoa

This type of microorganism…

• is a EUKARYOTE

• CELLULOSE cell walls

• found in saltwater, freshwater, and soil

• photosynthetic (produces O2 and carbohydrates)

• reproduces sexually OR asexually

algae

This type of microorganism…

• ACEULLULAR

• DNA or RNA core

• core is surrounded by a PROTEIN coat & coat may be enclosed in a lipid envelope

• replicated ONLY when IN a LIVING host cell (inert outside)

virus

This type of microorganism…

• is a EUKARYOTE

• MULTIcellular animals

• NOT strictly microorganisms

• consist of HELMINTHS (some microscopic stages in their life cycles), ectoparasites

multicellular animal parasites

EXTRA:

This type of FUNGI:

• is UNIcellular

yeasts

EXTRA:

These 2 types of FUNGI:

1. are both MULTIcellular

2. this ONE consists of masses of MYCELIA, which are composed of filaments called HYPHAE

1. molds and mushrooms

2. molds

EXTRA:

Name the type of ARCHAEA:

• are found in different ANAEROBIC habitats

• produce METHANE as a by-product of energy metabolism

methanogens

EXTRA:

Name this type of ARCHAEA:

• require HIGH SALT concentration for growth

• found in: Dead Sea

extreme halophiles

EXTRA:

name this type of ARCHAEA:

• can endure/ thrive in extreme temperatures

• found in: deep sea or hot springs in yellowstone national park

extreme thermopiiles
