Chapter 6 A Tour of the Cell
This chapter introduces the topics of microscopy and cell fractionation, followed by a review of
the cell and the major organelles and structures of eukaryotic cells. A challenge with this
chapter is to keep this data from simply being a list of parts. In addition to the structure and
function of individual organelles, questions probe student understanding of the cell as a
dynamic, interconnected system: the flow of membrane and proteins in the endomembrane
system to the plasma membrane; the flow of information from the nucleus to the cytoplasm;
and the connection between the cytoskeleton, the plasma membrane, and the extracellular
matrix. An evolutionary perspective goes beyond structural distinctions between prokaryotes
and eukaryotes to examine theories concerning the evolutionary origins of eukaryotes and key
eukaryotic cell structures.
1) A mycoplasma is an organism with a diameter between 0.1 and 1.0 µm. What does the
organism's size tell you about how it might be classified?
A) It must be a single-celled protist.
B) It must be a single-celled fungus.
,C) It could be almost any typical bacterium.
D) It could be a typical virus.
E) It could be a very small bacterium. - ✔✔Answer: E
Topic: Concept 6.2
Skill: Application/Analysis
2) Which of the following is a major cause of the size limits for certain types of cells?
A) limitation on the strength and integrity of the plasma membrane as cell size increases
B) the difference in plasma membranes between prokaryotes and eukaryotes
C) evolutionary progression in cell size; more primitive cells have smaller sizes
D) the need for a surface area of sufficient area to support the cell's metabolic needs
E) rigid cell walls that limit cell size expansion - ✔✔Answer: D

3) Which of the following statements concerning bacteria and archaea cells is correct?
A) Archaea cells contain small membrane-enclosed organelles; bacteria do not.
B) Archaea cells contain a membrane-bound nucleus; bacteria do not.
C) DNA is present in both archaea cells and bacteria cells.
D) DNA is present in the mitochondria of both bacteria and archaea cells. - ✔✔Answer: A

4) The evolution of eukaryotic cells most likely involved
,A) endosymbiosis of an aerobic bacterium in a larger host cell-the endosymbiont evolved into
mitochondria.
B) anaerobic archaea taking up residence inside a larger bacterial host cell to escape toxic
oxygen-the anaerobic bacterium evolved into chloroplasts.
C) an endosymbiotic fungal cell evolved into the nucleus.
D) acquisition of an endomembrane system, and subsequent evolution of mitochondria from a
portion of the Golgi. - ✔✔Answer: A

9) The nuclear lamina is an array of filaments on the inner side of the nuclear membrane. If a
method were found that could cause the lamina to fall into disarray, what would you expect to
be the most likely consequence?
