Prescott's Microbiology, 11e (Willey) Chapter 01: The Evolution of Microorganisms and Microbiology 1) Extant microorganisms are organisms from the fossil record that are no longer present on Earth today. Answer: FALSE Topic: Taxonomy of Microorganisms Bloom's/Accessibility: 2. Understand / Keyboard Navigation ASM Topic: Module 01 Evolution ASM Objective: 01.05 The evolutionary relatedness of organisms is best reflected in phylogenetic trees. Learning Outcome: 01.02a Propose a timeline of the origin and history of microbial life and integrate supporting evidence into it 2) All cellular organisms can be placed into one of three Archaea, and the Eukarya. , which include the Bacteria, Answer: domains Topic: Taxonomy of Microorganisms Bloom's/Accessibility: 2. Understand / Keyboard Navigation ASM Topic: Module 01 Evolution ASM Objective: 01.05 The evolutionary relatedness of organisms is best reflected in phylogenetic trees. Learning Outcome: 01.01b Explain Carl Woeses contributions in establishing the three-domain system for classifying cellular life 3) Archaea are cellular organisms that have unique cell membrane . Answer: lipids Topic: Archaea Bloom's/Accessibility: 1. Remember / Keyboard Navigation ASM Topic: Module 02 Cell Structure and Function ASM Objective: 02.03 Bacteria and Archaea have specialized structures (e.g. flagella, endospores, and pili) that often confer critical capabilities. Learning Outcome: 01.01c Determine the type of microbe (e.g., bacterium, fungus, etc.) when given a description of a newly discovered one 4) Microbiologists study a variety of organisms, but all are considered either Bacteria or Archaea. Answer: FALSE Topic: Taxonomy of Microorganisms Bloom's/Accessibility: 2. Understand / Keyboard Navigation ASM Topic: Module 05 Microbial Systems ASM Objective: 05.04 Microorganisms, cellular and viral, can interact with both human and nonhuman hosts in beneficial, neutral or detrimental ways. Learning Outcome: 01.01a Define the term microbiology 5) All eukaryotes have a membrane-delimited nucleus. Answer: TRUE Topic: Taxonomy of Microorganisms Bloom's/Accessibility: 2. Understand / Keyboard Navigation ASM Topic: Module 02 Cell Structure and Function ASM Objective: 02.04 While microscopic eukaryotes (for example, fungi, protozoa and algae) carry out some of the same processes as bacteria, many of the cellular properties are fundamentally different. Learning Outcome: 01.01c Determine the type of microbe (e.g., bacterium, fungus, etc.) when given a description of a newly discovered one 6) Viruses are not generally studied by microbiologists because they are not classified as living organisms. Answer: FALSE Topic: Taxonomy of Microorganisms Bloom's/Accessibility: 2. Understand / Keyboard Navigation ASM Topic: Module 05 Microbial Systems ASM Objective: 02.05 The replication cycles of viruses (lytic and lysogenic) differ among viruses and are determined by their unique structures and genomes. Learning Outcome: 01.01a Define the term microbiology 7) Viruses constitute the fourth domain of life in current biological classification schemes. Answer: FALSE Topic: Taxonomy of Microorganisms Bloom's/Accessibility: 2. Understand / Keyboard Navigation ASM Topic: Module 01 Evolution ASM Objective: 01.05 The evolutionary relatedness of organisms is best reflected in phylogenetic trees. Learning Outcome: 01.01b Explain Carl Woeses contributions in establishing the three-domain system for classifying cellular life
