Answer: A
A microscopic, unicellular organism that has acell wall impregnated with silicon and is important as plankton in a food chain belongsto which of the following groups?
a.Mossesb.Diatomsc.Cyanobacteria (blue-green algae)d.Fernse.Brown algae
Answer: B
Cell Fractionation
ChromatographyChromatographyElectrophoresisElectrophoresis
•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” ofprokaryotic 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 followingthree pairs of polymers:
Pair 1: tubulin…myosinPair 2: cellulose…chitinPair 3: messenger RNA…transfer RNA
For each of the three polymers you have chosen,describe its
a. structure, andb. role in a cell or organism
2006- A major distinction between prokaryotes andeukaryotes is the presence of membrane-boundorganelles in eukaryotes.
(a) Describe the structure and function of TWOeukaryotic membrane-bound organelles otherthan the nucleus.(b) Prokaryotic and eukaryotic cells have somenon-membrane-bound components in common.Describe the function of TWO of the following anddiscuss how each differs in prokaryotes and
eukaryotes. DNA Cell wall Ribosomes
(c) Explain the endosymbiotic theory of the originof eukaryotic cells and discuss an example of evidence supporting this theory.
