Characteristics of Bacteria I
Characteristics of Bacteria II
Characteristics of Bacteria III
Viruses I
100
The kingdom or domain of bacteria that are characterized by the lack of peptidoglycan in the cell wall and unusual lipids in the cell membrane
What is Archaebacteria?
100
Bacteria that are round and spherical in shape
What are cocci?
100
Bacteria, like cyanobacteria, that use sunlight to make energy
What are photoautotrophs?
100
Asexual reproduction in which bacteria copy their genetic information and divide in half
What is binary fission?
100
The outer protein coat of a virus
What is a capsid?
200
The kingdom or domain of bacteria that are characterized by having peptidoglycan in the cell wall
What is Eubacteria?
200
Bacteria that are rod-shaped
What are bacilli?
200
Bacteria that obtain energy by feeding on dead and decaying matter
What are saprobes?
200
Sexual reproduction in bacteria in which DNA is exchanged through joined pili
What is conjugation?
200
A virus that infects bacteria
What is a bacteriophage?
300
When exposed to Gram stain, these bacteria turn violet in color
What is Gram-positive bacteria?
300
Bacteria that are spiral-shaped
What are spirilla?
300
Bacteria that make energy by using chemicals instead of light
What are chemoautotrophs?
300
A structure that allows bacteria to go dormant; it contains cytoplasm and DNA encased in a tough coating
What is an endospore?
300
A process by which a bacteriophage enters a host cell, makes copies of itself, and then destroys the host cell when new viruses are released
What is a lytic infection?
400
When exposed to Gram stain, these bacteria turn pink in color
What is Gram-negative?
400
Spherical-shaped bacteria that live in long chains
What are streptococci?
400
Bacteria that require oxygen to live
What are obligate aerobes?
400
A type of chemical that inhibits the growth of bacteria
What is a disinfectant?
400
A process by which the genetic code of a bacteriophage is replicated with the host cell's DNA for a period of time without destroying the cell
What is a lysogenic infection?
500
A group of anaerobic bacteria that make energy by converting hydrogen and carbon dioxide into methane gas.
What are methanogens?
500
Spherical-shaped bacteria that live in clusters
What are staphylococci?
500
Bacteria that cannot survive in the presence of oxygen
What are obligate anaerobes?
500
A disease-causing bacteria
What is a pathogen?
500
A piece of a bacteriophage's genetic code that is embedded in the host's DNA during the lysogenic cycle
What is a prophage?
