1
the “brains” of the cell, hold DNA (chromosomes), and directs cell activity
2
makes protein
3
make, processes, and packages proteins, AKA: UPS
4
breaks down food with digestive enzymes
5
AKA:intracellular highway, transports things around the cell
6
makes energy (ATP) out of food also known as “powerhouse” of the cell
7
organizing, classifying, and naming living things formal system
8
assigning names
9
orderly arrangement of organisms into groups
10
domain, kingdom, phylum, class, order, family, genus, species
11
write genus first and capitalized then species second lowercase and underlined
12
inoculation, incubation, isolation, inspection, identification
13
placing a sample into a container of medium that supplies nutrients for growth and is the first stage in culturing
14
to increase visibility; makes it possible to handle and manage microbes in an artificial environment
15
exposing the inoculated medium to optimal growth conditions, generally for a few hours to days
16
to promote multiplication/produce the actual culture
17
methods for separating individual microbes and achieving isolated colonies that can be readily distinguished from one to another macroscopically
18
to make additional cultures from single colonies to ensure they are pure; that is containing only a single species of microbe for further observation/testing
19
observing cultures macroscopically for appearance of growth and microscopically for appearance of cells
20
to analyze initial characters of microbes in samples; stains of cells may reveal information on cell type and morphology
21
analysis of connected data to help support a final determination of the types of microbes presentation the original sample.
22
it lays the ground work for further research into the nature and roles of these microbes; it can also provide numerous application in infection diagnosis
23
suppress unwanted microbes and encourage desired microbes
24
mannitol salt agar contains high levels of salt that inhibits the growth of certain microbes
25
makes it easy to distinguish colonies of different microbes
26
rich in minerals and nutrients and are often used for growing a wide variety of microorganisms
27
consists of ingredients whose chemical formulas are known. these pure substances are carefully measured and dissolved in double distilled water
28
cheaper, can look at living specimens, good for cells but not organelle detail
29
poor depth of field, can’t get much in focus at higher magnifications, not a sharp image, resolution to 2 um as compared to 2 nm for EM
30
great depth of field, great resolution, 2nm
31
very costly, have to kill specimen to view it, specimen prep is involved; killed, fixed, coated
32
use one type of stain, uses common simple stain dyes such as crystal violet and safranin
33
uses 2 dyes; primary/counter stain, the 2 dyes are used for differentiating between 2 cell types/cell parts
34
gram stain
35
capsules, fimbriae, pili, flagella, cell wall
36
ribosome, cell membrane, slime layer, mesosome, actin filaments, chromosome, pilus, cytoplasmic matrix
37
bacillus: rod shaped coccus: spherical shaped spirilium: spiral shaped
38
diplococcus- bacteria that occurs in pairs of cocci streptococcus- chains/pairs of gram + coccus streptobacillus- gram - rod shaped and grouped in chains
39
prevents recognition and deconstruction of the bacteria by the immune cells and acts as a barrier for a cell from its surroundings and provides protection
40
monotrichous-single flagellum at one end lophotrichous-small bunches from the same site amphitrichous-flagella at both ends of the cell peritrichous-flagella dispersed over surface of cell
41
surrounded by a thin peptidoglycan cell wall which is surrounded by an outer membrane containing lippolysaccharide
42
bacteria lacks an outer membrane but are surrounded by layer of peptidoglycan many times thicker than is found in the gram negative
43
lippolysaccharides- can be toxic if released during infections, can block immune response
44
multicellular
45
unicellular
46
medium is a single nutrient prepared for microbial growth
47
media is multiple nutrients prepared for microbial growth
48
the absence of contamination by unwanted organisms
49
sterile technique, meaning that sterile media and inoculating tools must be used
50
surface coating made of sugars and or proteins
51
filament, hook, basal body
