The main category of bacteria which are curved, or twisted in shape, are referred to as:

Spiral

This general category of bacteria normally occur singularly and do not have multi-cell arrangements:

Spiral

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:

Spirochete

Embalmers should be aware that some bacteria are much harder to kill in the prep room because they can form this structure within the cell:

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

Eukaryotic

The study of immunity is called:

Immunology

Microbiology

The unit of measurement for microorganisms is the:

Micron/Micrometer

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:

Virus

Single celled fungi are called:

Yeasts

The group of organisms called fungi includes:

Yeasts and Molds

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
