common characteristics of all monerans
unicellular
sometimes colonial
prokaryotic
have ribosomes
no protein on chromosomes
heterotroph via absorption
some autotraph via photosynthesis or chemosynthesis
a sexual- binary fission
primative sexual by conjunction , transformation, transduction
have cell wall
Basic structure of a prokaryotic cell
cell membrane
cell wall
capsule
slime layer
chromosome
plasmid
ribosomes
flagella
pili (pilus)
endospore
Basic structure of a
eukaryotic cell
cell membrane
chloraphyll
chloroplasts
ribosomes
nuclear membrane
dna
mitochondria
form (shape type of cell wall)of monerans
cocci -shaped like spheres
bacilli- shaped like rods
sprilli - spiral shaped
_____________________________
cell wall= composed of peptidogicyan (protien+ carbohydrate)
Respiration equation
C6H12O6---->CO2+H20+ATP
Gram positive
protein/sugar = peptidogcylan
Gram negative
fat / sugar layer =lipid
protein/sugar = peptidogcylan
Motility of monerans
in order for a moneran to move it must have flagella(long whip like projections that allow for movement by rotating rapidly)
Ecological role of monerans
PRODUCERS( organism that is able to make its own food from inorganic substances)

DECOMPOSERS(organism that breaks down and obtains energy from dead organic material)

Parasites(organisms that survive by living and feeding either inside or attached to outer surfaces of another organism- doing harm to the host)
NITROGEN FIXERS(kive in hodules in roots of some plants)
Autotroph
make their own organic molicules from CO2
Heterotrophs
can't make their own oganic molecules
* must take in from surroundings via absorption
4 Human diseases caused by monerans
gangrene
tuberculosis
bubonic plague
tyroid fever
scarlet fever
obligate anaerobes
fermentation only
cant survive with O2
can survive without out O2
Faculative Anaerobes
fermentation and respiration
can survive with O2
can survive without O2
Obligate aerobes
respiration only
can survive with O2
cant survive without O2
Fermentation equation
C3H6O3+2ATP+C2H6O+C2H4O2
Photosynthesis equation
and what monerans are photosynthetic
6CO2+6H20---->C6H12O6+6O2
=cyanbacteria
Decomposers (sprophytes) obtain their food
feed on dead organic matter
eg. plants animals
Parasites obtain their food
feed on or in bodies of living organisms and cause them harm
antibiotics
a chemical that selectively kills bacteria when it is taken into the body as a medicine
how do antibiotics prevent bacterial growth
antibiotics interfere with bacterial enzymes without harming hosts enzymes

NON SPECIFIC - kill beneficial bacteria as well as pathogens
prevents natural immunity from developing
overuse results in development of risistant strands of bacteria
How do pathogenic bacteria affect their host (two ways)
1.the bacteria can damage the hosts cells directly by breaking them down to use for food

2. the bacteria can produce toxins(poisons) which will damage the hosts tissues
Preventing pathogens from entering the body
sterilization- subjecting them to high temperatures or to chemical solutions called sisenfectants

Food processing - refridgeriate- boiling - frying- steaming.
specific ways
primary immune response
- production of anitbodies specific to the bacteria antigen by b-lymphocyte WBC

Secondary immune response
antibodies produces so quickly and in such large #'s that the disease never gets a chance to develop
non specific
skin
oil & sweat
mucus & hairs
cilia
acid and digestive enzymes
phagocytic cells- injest & destroy bacteria
fever- increased body temp. slows/stops bacteria from growth / reproduction
Binary Fission
occurs when conditions ar favourable
DNA replicates/divides in half
produces 2 new daughter cells
type of a sexual reproduction
Transformation
a bacterium absorbs DNA released by broken or dead bacterium


- gains new traits(genes) this way
eg. resistance to antibiotics
Conjunction
involves transfer of DNA (usually plasmid DNA) from one cell to another across a conjunction pilis
Parasitism
organism that survives by living and feeding either in or attached to outer surfaces of another organism- doing harm to the host.
Commensalism
symbiosis in which one member benefits and the other isnt harmed
mutualism
symbiosis in which two species live together in such away that they both benefit from the relationship
