The Evolution of Microorganisms and Microbiology
True / False Questions
1. Extant microorganisms are organisms from the fossil record that are no longer present on
Earth today.
FALSE
ASM Objective: 01.05 The evolutionary relatedness of organisms is best reflected in phylogenetic trees.
ASM Topic: Module 01 Evolution

,3. Archaea are cellular organisms that have unique cell membrane __________.
lipids
ASM Objective: 02.01 The structure and function of microorganisms have been revealed by the use of microscopy (including bright field,
phase contrast, fluorescent, and electron).
ASM Objective: 02.03 Bacteria and Archaea have specialized structures (e.g. flagella, endospores, and pili) that often confer critical
capabilities.

Blooms Level: 1. Remember
Learning Outcome: 01.01.04 Determine the type of microbe (e.g., bacterium, fungus, etc.) when given a description of a newly discovered
microbe
Learning Outcome: 01.02.02 Design a set of experiments that could be used to place a newly discovered cellular microbe on a phylogenetic
tree based on small subunit (SSU) rRNA sequences
Section: 01.01
Topic: Archaea
True / False Questions
4. Microbiologists study a variety of organisms, but all are considered either Bacteria or
Archaea.
FALSE
ASM Objective: 05.03 Microorganisms and their environment interact with and modify each other.
ASM Objective: 05.04 Microorganisms, cellular and viral, can interact with both human and nonhuman hosts in beneficial, neutral or
detrimental ways.
ASM Topic: Module 05 Microbial Systems
Blooms Level: 2. Understand
Learning Outcome: 01.01.01 Differentiate the biological entities studied by microbiologists from those studied by other biologists

5. All eukaryotes have a membrane-delimited nucleus.
TRUE
ASM Objective: 02.01 The structure and function of microorganisms have been revealed by the use of microscopy (including bright field,
phase contrast, fluorescent, and electron).
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.
