A spiral shaped bacteria which is rigid when in motion is called a:
Spirillum
A spiral shaped bacteria which bends when in motion is a:

Tetrads
The study of bacteria is:
Bacteriology
This laboratory procedure is used to help identify bacteria by indicating what color they appear:
Gram Stain
Bacteria which are living in a favorable environment are said to be in a ______ state:
Vegetative
A spiral bacteria which is curved, or comma shaped is a:
Vibrio
Microorganisms with a true, organized nucleus are called:
Eukaryotic
The study of immunity is called:
Immunology
The study of small, living organisms, which can't be seen without a microscope is:
Microbiology
The unit of measurement for microorganisms is the:
Micron/Micrometer
Because bacteria lack a true, organized nucleus, they are referred to as being:
Prokaryotic
Microscopic, one celled animals are called:
Protozoa
Rod-shaped bacteria which are arranged end to end in chains are called:
Streptobacilli
The study of viruses is called:
Virology
The relative ability of a bacterial cell to cause disease is referred to as:
Virulence
This type of organism is not capable of independent life processes and must use components of another living cell in order to exist:
Virus
What type of organism is the smallest of all organisms?
Virus
Single celled fungi are called:
Yeasts
The group of organisms called fungi includes:
Yeasts and Molds
Rod or cylindrical bacteria are called:
bacillus

diplococci
A micrometer is about ______ of a millimeter
1/1000th
A micrometer is about ______ of an inch
1/25,000th
Which category of organism reproduces by a process called binary fission?
Bacteria
A gel-like envelope around the outside of some bacterial cells is called a:
Capsule
The external structure helps protect some bacteria by defending against an unfavorable environment:
Capsule
This bacterial structure helps some bacteria resist being attacked by the body's defense system:
Capsule
The external covering around a bacterial cell is called the:
Cell Wall
Immediately interior to the cell wall of a bacterium is the:
Cell membrane
The term "semi permeable" is given to this bacterial cell structure because it only allows certain substances to enter or leave the cell:
Cell membrane
What are the three main shapes of bacterial cells:
Coccus, Bacillus, Spiral
Round or spherical shaped bacteria are called
Coccus/Cocci
Rod shaped bacteria which appear as two cells attached together are called:
Diplobacilli
A bacterial cell which can produce either of these structures is capable of better resisting drying, heat, and chemicals:
Endospore and Capsule
Structures which can be formed within certain bacterial cells to protect them form unfavorable conditions are called:
Endospores
Whip-like structures on some bacterial cells which help provide movement are called:
Flagella
When conditions become favorable for a bacterial spore it may form a new cell in a process called:
Germenation
Protection which a person gains against disease producing organisms is called:
Immunization
Muti-celled fungi are called:
Molds
The study of the shape and size of organisms is called:
Morphology
The study of fungi is:
Mycology
In bacteria which have no organized nucleus, their nuclear material is scattered throughout the cell and is referred to as:
Nuclear bodies
The study of protozoa is called:
Protozoology
A group of diseases called typhus fevers are produced by what type of organism?
Rickettsiae
The study of rickettsia is called:
Rickettsiology
