, Chapter 1: The Evolution of Microorganisms and Microbiology
1) Archaea are cellular organisms that have unique cell membrane .
Correct 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
2) Extant microorganisms are organisms from the fossil record that are no longer present on Earth today.
Correct 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
3) All cellular organisms can be placed into one of three , which include the Bacteria, Archaea, and the
Eukarya.
Correct Answer: domains

, 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
5) Microbiologists study a variety of organisms, but all are considered either Bacteria or Archaea.
Correct 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
6) All eukaryotes have a membrane-delimited nucleus.
Correct 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
