BIO 103 Lecture Exam 5 Study
Guide questions and answers
What is taxonomy? - correct answer The science of naming and classifying organisms.
Who is the "Father" of Taxonomy? - correct answer Carolus Linnaeus
Binomial nomenclature - correct answer Each species is assigned a unique two-part name. The first part
is a noun that designates the genus and the second part is an adjective that modifies the noun called
specific epithet. Modern hierarchy system of classification.
Rules for scientific naming - correct answer 1. Typically latinized
2. Two part name: Genus and species
3. Genus is capitalized and species is lowercase
4. Complete name is italicized or underlined
Taxon - correct answer Generic name for taxonomic groups that are based upon characteristics/traits.
Correct order of taxa (taxons) - correct answer Domain, Kingdom, phylum, class, order, family, genus,
species
Three domains currently accepted by science - correct answer Bacteria, Archaea, Eukarya
Characteristics of organisms in Bacteria - correct answer 1. unicellular - microscopic, 1-10 um long
2. prokaryotic - "before a nucleus"
3. cell wall (peptidoglycan)
4. glycocalyx(capsule or slime layer) or glycoprotein
5. Flagella(some)
6. fimbriae- short hairlike filaments (some)
, 7. nucleoid 1 circular chromosome
8. plasmid (accessory ring of DNA) (some)
9. ribosomes....fewer & smaller
10. thylakoids(some) 11. Heterotrophic
Characteristics of organisms in Archaea - correct answer 1. Prokaryotes
2. Unicellular
3. microscopic
4. Peptidoglycan absent in cell walls
Characteristics of organisms in Eukarya - correct answer 1. No peptidoglycan
2.Has nucleus and organelles 3.Cell wall (ether lipids)
How many kingdoms are in domain Eukarya - correct answer 4; Protists, Plantae, Fungi, Animalia
Why was Kingdom Monera divided into Domains Bacteria and Archaea? - correct answer There was a lot
of them so they got moved into a biggr category.
Characteristics of kingdom fungi - correct answer 1. Eukaryotic
2. Most Fungi are multicellular
3. Heterotroph by absorbtion
4. Chitin Cell Walls- Composed of mainly nitrogen
5. No motile stage
6.Adult form is haploid, zygote is diploid, the zygote splits into haploid spores
7. Asexual
8. Hyphae- Tiny filaments composed of tubular cell walls filled with protoplasm
9. Mycelium- A mass of intertwined hyphae
10. Septate- Walls that divide the hyphae into individual cells
11. Has no septate
