History & Applications
Who performed the Swan Neck Flask experiment?
Who is Louis Pasteur?
This double-layered structure surrounds all cells and is made of phospholipids.
Cell membrane
The three domains of life
Bacteria, Archaea, Eukaryota
Prokaryotic DNA is usually stored in this central structure.
Nucleoid
These cellular powerhouses may have evolved from prokaryotes.
Mitochondria
The abbreviated form of Escherichia coli used in writing.
E. coli
This German physician experimentally proved that specific microbes were the causative agents for specific diseases
Who is Robert Koch?
This structure is responsible for protein packaging and modification in eukaryotic cells AKA the post office of the cell
Golgi apparatus
This molecule’s analysis led to the classification of Archaea as a separate domain.
16S rRNA
This spiral-shaped bacterium moves via periplasmic flagella.
Spirochete
This internal network of membranes is “rough” due to its ribosomes.
Rough ER
This term describes microbes that cause disease.
Pathogens
Which process uses microbes to detoxify harmful substances?
Bioremediation
The part of a protein that determines its function.
Shape/structure
This domain includes all organisms with membrane-bound organelles.
Eukaryotes
This process allows bacteria to transfer DNA using a pilus.
Conjugation
These microbes are eukaryotic and often cause infections that are difficult to treat.
Fungi
Protozoa
This macromolecule is used for long-term energy storage
Triglycerides
What term is used for a well-supported scientific explanation?
Theory
Bacterial ribosomes are what size/category? (#S)
70S
The presence or absence of peptidoglycan in the cell wall helps differentiate these domains.
Bacteria and archaea
This tough outer structure made of sugars and peptides provides support in bacteria.
Peptidoglycan
This type of worm is multicellular and has a well-developed reproductive system.
Parasitic worm (helminth)
This form of glycocalyx helps prevent dehydration in bacteria.
Slime layer
What process allows microbes to adapt over time to survive anywhere?
Evolution
This waxy molecule in Mycobacterium contributes to its resistance to antibiotics.
Mycolic acid
One reason treating infections caused by this domain is difficult is because their cells are like ours.
Eukaryotes
The outer membrane of Gram-negative bacteria contains these toxic fragments
Endotoxins
This structure stores the cell's genetic material in eukaryotic cells.
Nucleus
Bacteria move toward or away from chemical stimuli using this behavior.
Chemotaxis
Name a technique used to produce insulin using microbes.
Recombinant DNA technology
These hairlike structures help bacteria adhere to surfaces but are not used for movement.
Fimbriae
These are three structures a microbiologist might examine to identify a microbe’s domain.
Ribosomes, membrane composition, and presence of nucleus
The thick layer of this substance in Gram-positive bacteria retains the crystal violet stain.
Peptidoglycan
This theory explains how mitochondria and chloroplasts originated in eukaryotic cells.
Endosymbiotic theory/endosymbiosis
These three parts make up a nucleotide.
Ribose sugar
Phosphate group
Nitrogenous base
