Q

transport network of tubules and flattened sacs

A

Endoplasmic Reticulum

25
protein synthesis
Rough ER
26
detoxification
Smooth ER
27
“packaging plants” : completes the transformation of newly synthesized proteins into mature, functional ones and packages them into small, membrane-enclosed vesicles for storage within the cell or export outside the cell
Golgi complex
28
lysozyme and other digestive enzyme * autolysis : destroy entire cell
Lysosomes
29
catalase : catalyzes (speeds up) the breakdown of hydrogen peroxide into water and oxygen.
Peroxisomes
30
Powerhouse of the cell
mitochondria
31
sites of photosynthesis
Plastids
32
system of fibers * strengthen, support, and stiffen the cell, and give the cell its shape
Cytoskeleton
33
external structures that provide rigidity, shape, and protection * cellulose: algae, plants * chitin: fungi
Cell wall
34
whip-like * organelles of locomotion : “swim" through liquid environments
Flagella
35
hair-like * coordinated, rhythmic movement
Cilia
36
* consists of a single, long, supercoiled, circular DNA molecule * control center of the bacterial cell * suspended or embedded in the cytoplasm * plasmid: extrachromosomal DNA
Chromosome
37
highly organized and firmly attached to the cell wall * negative stain: a capsule staining procedure * The capsule appears as an unstained halo around the bacterial cell * antiphagocytic function: protecting the encapsulated bacteria from being phagocytized
capsule
38
thick layer of material located outside their cell wall
Glycocalyx
39
three, four, or more threads of protein twisted like a rope
flagellin
40
is a single structure that facilitates transfer of genetic material from one bacterial cell to another following attachment of the cells to each other
sex pilus
41
polymerized protein molecules
pilin
42
genetic material (usually in the form of a plasmid) is then transferred from the donor cell to the recipient cell
conjugation
43
enable bacteria to adhere or attach to surfaces
Fimbriae
44
formation of spores
sporulation
45
types of spore stains
a. terminal spore b. subterminal spore
46
have been shown to survive for many years in soil or dust, and some are quite resistant to disinfectants and boiling
Spores
47
* one cell (the parent cell) splits in half to become two daughter cells. * before a prokaryotic cell can divide in half, its chromosome must be duplicated (a process known as DNA replication), so that each daughter cell will possess the same genetic information as the parent cell * generation time: the time it takes for one prokaryotic cell to become two cell
Binary fission
48
Area of biological science for classification, nomenclature and identification of all living entities.
Taxonomy
49
the arrangement of organisms into taxonomic groups on the basis of similarities or relationships. Taxa include kingdoms or domains, divisions or phyla, classes, orders, families, genera, and species.
classification
50
the assignment of names to the various taxa according to international rules.
nomenclature
51
the process of determining whether an isolate belongs to one of the established
identification
52
simplest, single celled prokaryotic organisms * contains organisms that are broadly divided into three phenotypic categories: * based on their physical characteristics * Gram-negative and have a cell wall * Gram-positive and have a cell wall * those that lack a cell wall
Bacteria
53
are small infectious proteins that cause fatal neurologic diseases in animals and humans in which the brain becomes riddled with holes (becomes sponge-like) are thought to be transmit- ted by consumption of food contaminated with the agent * all these diseases are untreatable and fatal and are collectively referred to as transmissible spongiform encephalopathies (TSE) which involve loss of coordination and dementia
