IMED1004 2- Intro to microorganisms Exam Questions and Answers Solved Correctly Rated A+
Prokaryotic microorganisms and area of microbiology - Answers Bacteria (bacteriology) and archaea
Eukaryotic microorganisms and area of microbiology - Answers Protozoa (protozoology), fungi
(mycology), algae (phycology)
Acellular microorganisms and area of microbiology - Answers Viruses (virology) and prions
What is taxonomy - Answers Groups organisms on basis of similarity. DNA analysis provides further
evidence for relatedness.
Genus and species name example - Answers Genus- Esherichia
Species- E.coli
(all in italics)
Virulence factor - Answers Increases disease causing capacity
Structure of bacteria - Answers Capsule, pili, flagella, plasma membrane, rigid cell wall.
Role of capsule in bacteria - Answers Bacterial adherence, protection from immune response
Role of pili in bacteria - Answers Role in adherence
role of Flagella in bacteria - Answers For locomotion
Role of cell wall in bacteria - Answers Determines where bacteria can live, kind of disease they cause and
treatment options.
What is a gram stain and the two colours - Answers Differentiates between two main types of bacteria
by cell wall structure. Gram negative is pink and gran positive is purple.
Gram-negative bacteria structure - Answers Two membranes. Outer wall contains lipopolysaccharies
that when the bacteria dies liberate LPS to trigger immune reaction.
Gram-positive bacteria structure. - Answers Cell wall conposed of peptidoglycan, can survive in harsher
environments. Good colonisers of skin.
What are endospores - Answers They form in response to nutritional deprivation or harsh environments,
permits survival during this time. Growth can resume is conditions improve.
How many cells does fungi have - Answers Can be uni or multicellular. They are a diverse group of
eukaryotic microorganisms.
Example of a unicelllar fungi - Answers saccharomyces cerevisiae
Example of single celled yeast (fungi) - Answers Candida albicans
