Flashcards in Module 1: Characteristics of Microorganisms Deck (9):
1

a visible mass of bacteria on a solid medium that has grown from one bacterial cell

colony

2

a structure formed by some bacteria that allows the bacterium to remain dormant during periods of adverse conditions. These are more resistant to destruction than vegetative bacteria.

endospore

3

a virus particle surrounded by a lipid envelope

enveloped virus

4

the time required for a bacterial population to double

generation time

5

staining procedure carried out in the laboratory. Divides bacteria into two groups, Gram positive staining a blue-black colour and Gram negative staining a red colour.

Gram stain

6

the phases of growth (lag, log, stationary, death) bacteria go through when introduced into a culture medium

growth curve

7

a unit of the metric system used for measurement of microscopic objects (1,000 of these in one millimeter)

micrometer

8

a virus consisting of nucleic acid and protein but no lipid envelope

unenveloped (naked) virus

9

a bacterial cell that does not have an endospore

vegetative cell
