Microbiology 2060 SLCC WintersChapter 1-4 Exam 1
Microorganisms are very diverse and are found in all three domains of life: - answer
Archaea, Bacteria, and Eukarya.
Archaea and bacteria are classified as - answer Prokaryotes because they lack a
cellular nucleus.
Archaea inhabit nearly every environment on earth, but no archaea have been identified
as - answer human pathogens.
Eukaryotes studied in microbiology include - answer algae, protozoa, fungi, and
helminths.
Algae are plant-like organisms that can be either - answer unicellular or multicellular,
and derive energy via photosynthesis.
Protozoa are - answer unicellular organisms with complex cell structures; most are
motile.
Microscopic fungi include - answermolds and yeasts.
Helminths are - answermulticellular parasitic worms. They are included in the field of
microbiology because their eggs and larvae are often microscopic.
Viruses are - answeracellular microorganisms that require a host to reproduce.
Which of the following types of microorganisms is photosynthetic?
yeast
virus
helminth
alga - answerD
Which of the following is a prokaryotic microorganism?
helminth
protozoan
cyanobacterium
mold - answerC
,Which of the following is acellular?
virus
bacterium
fungus
protozoan - answerA
Which of the following is a type of fungal microorganism?
bacterium
protozoan
alga
yeast - answerD
Which of the following is not a subfield of microbiology?
bacteriology
botany
clinical microbiology
virology - answerB
A ________ is a disease-causing microorganism. - answerpathogen
Multicellular parasitic worms studied by microbiologists are called ___________. -
answerhelminths
The study of viruses is ___________. - answervirology
The cells of prokaryotic organisms lack a _______. - answernucleus
Describe the differences between bacteria and archaea. - answerArchaea have more
complex RNA polymerases than Bacteria.
Unlike bacteria, archaea cell walls do not contain peptidoglycan.
Archaea have different membrane lipid bonding from bacteria and eukarya. There are
genetic differences.
Name three structures that various protozoa use for locomotion. - answerThe three
structures utilized for locomotion by protozoa are flagella, cilia and pseudopodia.
Describe the actual and relative sizes of a virus, a bacterium, and a plant or animal cell.
- answerThe plants and animals are the multicellular eukaryotic organisms. The
approximate size (diameter) of most animal and plant cells ranges from 10 to 100 µm.
, A virus is smaller than a bacterium. They range in size from about 20 to 400
nanometres in diameter (1 nanometre = 10-9 meters).
Binomial nomenclature assigns - answerorganisms Latinized scientific names with a
genus and species designation.
A phylogenetic tree is a way of showing - answerhow different organisms are thought to
be related to one another from an evolutionary standpoint.
The first phylogenetic tree contained kingdoms for - answerplants and animals.
Ernst Haeckel proposed - answeradding kingdom for protists.
Robert Whittaker's tree contained - answerfive kingdoms: Animalia, Plantae, Protista,
Fungi, and Monera.
Carl Woese used small - answersubunit ribosomal RNA to create a phylogenetic tree
that groups organisms into three domains based on their genetic similarity.
Bergey's manuals of determinative and systemic bacteriology are the standard
references for - answeridentifying and classifying bacteria, respectively.
Bacteria can be identified through - answerbiochemical tests, DNA/RNA analysis, and
serological testing methods.
Which of the following was NOT a kingdom in Linnaeus's taxonomy?
animal
mineral
protist
plant - answerC
Which scientist proposed adding a kingdom for protists?
Carolus Linnaeus

sapiens
Which of the following is NOT a domain in Woese and Fox's phylogenetic tree?
Plantae
Bacteria
