cellular and acellular

Question 2

types of cellular microbes

Answer 2

fungi
protozoa
algae
bacteria
archaea

Question 3

types of acellular microbes

Answer 3

viruses
prions
viroids

Question 4

fungi

Answer 4

cellular microbes including yeast and mold

Question 5

protozoa

Answer 5

cellular microbes including giardia lambria

Question 6

bacteria

Answer 6

cellular microbes including mycobacterium tuberculosis

Question 7

archaea

Answer 7

cellular microbes including thermophilus acquaticus

Question 8

viruses

Answer 8

acellular microbes made up of a protein shell and nucleic acids (DNA or RNA, never both)
neither prokaryotic or eukaryotic
obligate intracellular parasites: can only reproduce in a host cell
do not eat or make waste
don’t grow in size, but do grow in number

Question 9

prions

Answer 9

acellular microbes made of proteins only

Question 10

viroids

Answer 10

acellular microbes made of RNA only

Question 11

prokaryotes

Answer 11

cells with no nucleus or membrane-bound organelles, for example bacteria and archaea

Question 12

eukaryotes

Answer 12

cells that have a nucleus and membrane-bound organelles, for example fungi, protozoa, and algae

Question 13

transitional organisms

Answer 13

organisms that may lack one or more membrane-bound organelles, but are still considered eukaryotes (for example, giardia)

Question 14

3 domains of microbes

Answer 14

1. bacteria
2. archaea
3. eukarya
   (categorizing cellular organisms by their rRNA sequences)

Question 15

naming bacteria

Answer 15

genus –> species –> strain
