Question 7

studied isolation of bacterial pure cultures using potato slices and gelatin

Answer 7

Robert Koch

Question 8

requires an atmosphere containing molecular oxygen in concentrations comparable to that found in room air (20-21%) in order to grow & multiply

Answer 8

Obligate aerobe

Question 9

requires oxygen for multiplication but in concentrations lower than that found in room air (about 5% oxygen)

Answer 9

Microaerophile / microaerophilic aerobe

Question 10

can only grow in an environment containing no oxygen

Answer 10

Obligate anaerobe

Question 11

does not require oxygen, grows better in the absence of oxygen, but can survive in atmospheres containing molecular oxygen

Answer 11

Aerotolerant anaerobe

Question 12

capable of surviving in either the presence or absence of oxygen (0% to 20-21% oxygen)

Answer 12

Facultative anaerobe

Question 13

Bacteria oxygen req na ara sa babaw ang tanan nga growth

Answer 13

Obligate aerobe

Question 14

bacteria oxygen req na damo2 sa babaw pero dutay sa iban nga parts

Answer 14

Facultative anaerobe

Question 15

bacteria oxygen req na even lang sa tanan

Answer 15

aeotolerant anaerobe

Question 16

bacteria oxygen req na ara tanan sa dalom ang growth

Answer 16

strict anaerobe

Question 17

grow better in the laboratory in the presence of increased concentrations of carbon dioxide

Answer 17

Capnophiles

Question 18

nutritionally demanding / “fussy”

Answer 18

Fastidious bacteria

Question 19

with a gram-negative cell wall; an obligate intracellular pathogen – appears to have a leaky cell membrane so it must live inside another cell to retain all necessary substances; transmitted by arthropod vectors

Answer 19

Rickettsia

Question 20

with a gram-negative cell wall; an obligate intracellular pathogen – lacks the enzymes required to perform many essential metabolic activities, particularly production of ATP molecules (sometimes called energy parasites); transmitted by inhalation of aerosols or by direct contact between hosts

Answer 20

Chlamydia

Question 21

does not produce oxygen; photosynthesis of purple & green bacteria

Answer 21

Anoxygenic photosynthesis

Question 21

– produces oxygen; photosynthesis of cyanobacteria

Answer 21

Oxygenic photosynthesis

Question 21

no cell wall; appears pleomorphic microscopically – assumes many shapes due to the lack of the cell wall; formerly called PPLO – pleuropneumonia-like organisms; free-living or parasitic and pathogenic to many plants and animals

Answer 21

Mycoplasma

Question 23

widely distributed in nature – exist in pond or lake water under appropriate conditions, but may grow profusely in both freshwater & seawater; some produce toxins which are harmful to birds, domestic animal & wild animals that consume pond or lake water containing the toxins

Answer 23

Cyanobacteria

Question 24

intracellular membranes in cyanobacteria where photosynthesis takes place; attached to the cell membrane at various points

Answer 24

thylakoids

Question 25

single-celled simple organisms which are more closely related genetically to eukaryotes than they are to bacteria (type of rRNA possessed – sequences different from that of bacteria but more closely related to eukaryotes); w/cell wall but no peptidoglycan

Answer 25
