Monera kingdom


type of cell

prokaryotic - lacks membrane bound organelles

uni or multi celled?

most are unicellular

nutrition

autotrophs-make their own food by photosynthesis.




heterotrophs-use the energy in some chemical compounds to produce food




saprobe and parasites- some cannot produce their own food.

saprobe

feeds on matter from dead organism


feed on the waste of organism




ex. the bacteria that feds on your sweat on your skin are saprobes.

parasites and hosts

parasite: the one that hurts the host on witch it feeds.


host : the one getting fed on.




bacteria that act as parasites include that cause diseases cholera, small pox, and the bubonic plague.

locomotion

flagella and cilia

cell wall?

some but not all

examples of moneras

bacteria and blue- green algae

phylums

2phya bacteria and cyanobacteria





characteristics



no nucleus


smallest and simplest kind of living thing


more moneras than any other organism

structure of the bacteria


what are the parts?

ribosomes
dna
cell wall
capsule
flagelum
plasmid 
chromosomes 
cell membrane

ribosomes


dna


cell wall


capsule


flagelum


plasmid


chromosomes


cell membrane

cocci bacteria

sphere shaped


an example is bacteria that cause strep throat.

bacilli bacteria

rod-shape


certain bacteria that live in your stomach are bacilli bacteria

spirilla bacteria

spiral shaped


best known, cause diseases


spirillum minus

respiration

aerobe: needs oxygen


anaerobe: dosent need oxygen




bacteria get their energy from breaking down of food in the process of respiration. some bacteria need oxygen to brake down their food and some do not.

reproduction

reproduction is by fission


fission is the simplest form of asexual reproduction y just one parent



sexual reproduction

the process in which one bacteria transfers genetic material to another through direct contact.

a.one bacteria transfers genetic material to another


b.the two cells are separated


c.the bacteria then divides by binary fission


d. results in genetically different bacteria.

what is an endospore

a small round, thick walled protective structure that forms inside a moneran cell during unfavorable conditions .it contains genetic material and some cytoplam.

are bacteria dangerous

most arent, but some can make you sick. those are called pathogens


pathogens can cause .....

dieases in animals and plants.


ex. leprosy, food poisoning, pneumonia, tetanus.

are all bacteria bad?

not at all, most bacteria are very helpful to us. they play an important role in the plants ecosystem.

bacteria in food?

yes there is.used when making food like yogurt,cheese , pickles and soy sauce.

bacteria in our bodies

a bacteria can help us digest our food soma assist our immune system.
