3. Site of modification and
packaging of proteins
and lipids prior to export
from the cell
E
Answer: C
D
A
4. Site of transport of
materials into and out of
the cell
Answer: D
5. Evolved from a
photoautotrophic
Answer: B
prokaryote
Membranes are components of all the
following EXCEPT:
a.
b.
c.
d.
e.
mictrotubule
nucleus
Golgi apparatus
mitochondrion
lysosome
Answer: A
A microscopic, unicellular organism that has a
cell wall impregnated with silicon and is
important as plankton in a food chain belongs
to which of the following groups?
a.
b.
c.
d.
e.
Mosses
Diatoms
Cyanobacteria (blue-green algae)
Ferns
Brown algae
Answer: B
Cell Fractionation
Electrophoresis
Chromatography
•All living matter is composed
of one or more cells
•The cell is the structural
and functional unit of life
•All cells from other cells
•No nucleus
•No membrane bound
organelles
•Smaller
•Older (evolutionary)
•Only bacteria
•Nucleus
•Various organelles
•Larger
•Newer (evolutionary)
•All other kingdoms
•Eukaryotes evolved as
“symbiotic consortiums” of
prokaryotic cells
•Have observed similar
behavior in amoebas
containing symbiotic
bacteria
•DNA evidence:
mitochondria, cholorplast,
centriole found to have own
DNA- different from
eukaryotic cell- more like
endosymbiotic bacteria
•Volume to surface area ratio
•Cell control
•Metabolic requirements

Answer: A
2002B- The physical form of cells and organisms
is often influenced by special structural polymers.
Choose one polymer from each of the following
three pairs of polymers:
Pair 1: tubulin…myosin
Pair 2: cellulose…chitin
Pair 3: messenger RNA…transfer RNA
For each of the three polymers you have chosen,
describe its
a. structure, and
b. role in a cell or organism
2006- A major distinction between prokaryotes and
eukaryotes is the presence of membrane-bound
organelles in eukaryotes.
(a) Describe the structure and function of TWO
eukaryotic membrane-bound organelles other
than the nucleus.
(b) Prokaryotic and eukaryotic cells have some
non-membrane-bound components in common.
Describe the function of TWO of the following and
discuss how each differs in prokaryotes and
eukaryotes.
DNA
Cell wall
Ribosomes
(c) Explain the endosymbiotic theory of the origin
of eukaryotic cells and discuss an example of
evidence supporting this theory.
