millimeter or 1/25,000 of an inch; usually designated by the Greek
letter "u".
Protoplasm Correct Answer Describes all living materials in a cell.
A thick mucous-like substance that is colorless and translucent
that forms the biochemical basis of life within the cell nucleus.
Components of a cell Correct Answer cell wall, cell membrane,
cytoplasm, capsule, flagella, nucleus
Phagotization Correct Answer The process by which some cells
can ingest bacteria or other foreign particles. (process where
white blood cells in the human body destroy bacteria by engulfing
them).
Cytoplasm Correct Answer The living matter of a cell between the
cell's membrane and nucleus.
,Nucleus Correct Answer The functional center of a cell that
governs activity and heredity.
DNA Correct Answer Deoxyribonucleic Acid. The protein found in
the chromosomes of a cell nucleus which is the basis of heredity..
Cell wall Correct Answer A tough rigid structure that helps
maintain the cell's shape.
Microbiology Correct Answer The study of microorganisms. The
science which treats the nature, life and action of microorganisms.
Contamination Correct Answer The state of being soiled or
infected by contact with infectious organisms or other material
Cell membrane Correct Answer This layer is located just beneath
the cell wall which is semi-permeable.
Capsule Correct Answer A mucus material that protects the
bacteria from the host cells that try to destroy it.
Flagella Correct Answer Thread-like tails attached to the cell that
enable the bacteria to move through liquids.
,Acid-fast bacteria Correct Answer Mycobacterium tuberculosis
(which causes tuberculosis) and Mycobacterium leprae (which
cause leprosy).
Spore Correct Answer Microrganisms capable of forming a thick
wall around themselves enabling them to survive in adverse
conditions; a resistant form of bacterium.

Enterococcus bacteria that are no longer sensitive to Vancomycin.
Virus Correct Answer One of a group of minute infections agents
that grow only in living tissues or cells.
Host Correct Answer The animal, plant, or human that supports
the growth of microorganisms.
