Unit 03: Prokaryotic Cells Knowledge Audit (final)
“This final Knowledge Audit will gauge your understanding of the material for the "Cell Theory" unit after instruction has ended. Your teacher will use the information to see where you have grown and what you still feel you need to improve on. Please answer each question accurately and honestly. Questions posed at the end will be answered (quickly) before the quiz is given."

Syllabus Statements
For each statement below, indicate your level of confidence and knowledge about the statement using the following scale:
1. Very poor: you've never heard of this topic or idea.
2. Poor: you've heard this, but couldn't tell share any detailed information about it.
3. Fair: you remember the basic information about this topic or idea.
4. Good: you remember details and examples about this topic or idea.
5. Very good: you could teach others about this topic or idea.
1.2.U1: Prokaryotes have a simple cell structure without compartmentalization. *
Outline the major differences between prokaryotic and eukaryotic cells. List the functions of the following structures of a prokaryotic cell: cell membrane, nucleoid, plasmid, cytoplasm, ribosome, cell wall, pili, capsule, flagella Define extracellular. Contrast the size of eukaryotic and prokaryotic ribosomes.
Very Poor
Very Good
1.5.U2: The first cells must have arisen from non-living material. *
Outline the four processes needed for the spontaneous origin of cells on Earth. Outline the experiments of Miller and Urey into the origin of organic compounds. Define polymerization, monomer and polymer. Outline two properties of RNA that would have allowed it to play a role in the origin of life.
Very Poor
Very Good
1.2.S1: Drawings of the ultrastructure of prokaryotic cells based on electron micrographs. *
Explain why the ultrastructure of prokaryotic cells must be based on electron micrographs. Draw the ultrastructure of E.coli, including the cell wall, pili, flagella, plasma membrane, cytoplasm, 70s ribosomes, and nucleoid with naked DNA.
Very Poor
Very Good
3.2.U1: Prokaryotes have one chromosome consisting of a circular DNA molecule. *
Describe the arrangement of prokaryotic DNA (nucleoid and plasmid). Define the term “naked” in relation to prokaryotic DNA.
Very Poor
Very Good
3.2.U2: Some prokaryotes also have plasmids but eukaryotes do not *
Describe the structure and function of plasmid DNA.

1.2.U3: Prokaryotes divide by binary fission. *
Define asexual reproduction. Outline the four steps of binary fission.
Very Poor
Very Good
6.3.U7: Antibiotic blocks processes that occur in prokaryotic cells but not in eukaryotic cells. *
Define antibiotic. Outline the mechanisms by which antibiotics kill bacteria.
Very Poor
Very Good
6.3.A3: Florey and Chain’s experiments to test penicillin on bacterial infections in mice. *
Explain methods and results of Florey and Chain’s experiments.
Very Poor
Very Good
6.3.NOS: Risks associated with scientific research- Florey and Chain’s tests on the safety of penicillin would not be compliant with current protocol on testing. *
Compare allowable research risks of the past with those of the present.
Very Poor
Very Good
6.3.U8: Viruses lack a metabolism and cannot therefore be treated with antibiotics *
Explain why antibiotics are ineffective against viruses.
Very Poor
Very Good
