chapter 10


List the major characteristics used to differentiate the
three kingdoms of multicellular Eukarya.

- animalia: multicellular; no cell walls; chemoheterotrophic
- plantae: multicellular; cellulose cell walls; usually photoautotrophic
- fungi: chemoheterotrophic; unicellular or multicellular; cell
walls of chitin; developed from spores or hyphal fragments


7. Define protist.

- a catchall kingdom for eukaryotic organisms that do not fit other
kingdoms; grouped into clades based on rRNA


Differentiate eukaryotic, prokaryotic, and viral species.

#NAME?


Explain the purpose of Bergey's Manual.

#NAME?


Describe how staining and biochemical tests are used to
identify bacteria.

#NAME?


Differentiate culture, clone, and strain.

#NAME?


Explain why scientific names are used.

#NAME?

?3. List the characteristics of Bacteria, Archaea, and
Eukarya domains.

- Bacteria- prokaryotic, cell wall contains peptidoglycan, membrane
lipids are composed of straight carbon chains
attached to glycerol by phospholipid ester linkage, antibiotic
sensitivity, rRNA loop is present, common arm of tRNA is present
- Archaea- prokaryotic, cell wall varies in composition; contains no
peptidoglycan, membrane lipids are composed of
branched carbon chains attached to glycerol by ether linkage, no
antibiotic sensitivity, rRNA loop is lacking and common arm of tRNA is lacking
- eukarya- eukaryotic, cell wall varies in composition; contains
carbohydrates,no antibiotic resistance, rRNA loop is lacking, Common
arm of tRNA is present


2. Discuss the advantages of the three-domain system.

- all organisms evolved from cells that formed over 3 billion years
ago, the DNA passed on from ancestors is described
as conserved, ribosomes are not the same in all cells-showed they
are distinctly different cell groups

?1.Define taxonomy, taxon, and phylogeny.

taxonomy- the science of classifying organisms
- taxon- to show degrees of similarities among organisms
- phylogeny- the study of the evolutionary history of organisms
