C3 CLASSIFICATION OF MICROORGANISM Flashcards
1
Q
pathogen
A
capable of causing disease
2
Q
nonpathogen
A
no harmful effect
3
Q
normal flora
A
colonies of nonpathogens
4
Q
2 types of cells
A
- eukaryotes
- prokaryotes
5
Q
prokaryotes
A
- lacks nucleus
- bacteria, virus
- unicellular
6
Q
eukaryotes
A
- has nucleus
- multicellular
7
Q
diagram of bacterial cell
INGAT !! (page 8)
A
- capsule layer 1
- cell wall layer 2
- cell membrane layer 3
- ribosome bintik ii
- chromosomal DNA mcm benang
- flagellum mcm ekor
- pilus mcm duri
8
Q
bacteria
A
- cell wall consist of peptidoglycan
- gram + = thick peptidoglycan layer IN CELL WALL
- gram - = thin peptidoglycan layer and an OUTER MEMBRANE
- func = provides shape and support
= give rigidity
9
Q
cell membrane
A
- made up of PROTEIN, CARBOHYDRATE, LIPID
- control movement of nutrient and waste
10
Q
cytoplasm (can be asked)
A
- cellular growth, metabolism and replication
- sustain the life
11
Q
ribosome
A
protein synthesis
12
Q
plasmid
A
to exchange dna between bacterial cells
13
Q
flagella
A
- organ of locomotion/mortility
- chemotaxis = movement in response to chemical
- chemotaxis - movement towards nutrient
- chemotaxis - away from harmful chemical
14
Q
capsule
A
- protect cell from phagocytosis
15
Q
bacterial shape
A
- spirilla - mcm spring
- bacilli - mcm pil tablet (rod-shaped)
- cocci - bulat ii
16
Q
identification of bacteria
A
- staining
- gram + = retain the stain ( purple)
- gram - = loosing the stain ( pink/red)
# - lg bahaya dr +
- culture
17
Q
recap about bacteria
A
- bacteria are classified based on their shapes, need for oxygen and gram-staining properties.
- aerobic = need O2 to grow
- anaerobic = doesn’t need O2
- staphylococci - grape-like clusters
- streptococcus - appears in chain
- diplococci - appears in pairs
18
Q
virus
A
- replicates/reproduce only inside the living cells of other organism
- called obligate intracellular parasite because CAN ONLY GROW AND LIVE INSIDE ANOTHER LIVING CELLS
19
Q
structure
A
- envelope = inner core of nucleic acid surrounded by a protein coat
- naked viruses = lack an envelope
- virion = infectious virus particle
20
Q
life cycle
A
- attachment
- penetration ( inject it’s dna )
- replication
- assembly ( into mature virus)
- release ( lysis and release )
21
Q
fungi
A
- eukaryotic organism
- no chlorophyll
- spores = fungi reproduce
- direct source of food
- mushroom and truffle
- fermentation food product
- wine, beer, soy sauce
- antibiotics
- produce mycotoxins = toxic
22
Q
mycosis
A
fungal infection in human
23
Q
how fungal infection occurs
A
when the balance of normal flora is altered by antibiotic therapy
24
Q
blue-green algae
A
can cause disease
