1. Site of glucose synthesis Answer: B B 2. Site of conversion of chemical energy of glucose to ATP C Answer: A 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 Anatomy of the Animal Cell 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.

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 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.
