The kingdoms that contain the oldest forms of life on earth.
Eubacteria and Archaebacteria
As a cell grows ,
the chromosoms become seperated.
The chromosome and it's copy attatch to
the inside of the cell membrane.
Before cell division the chromosome is
replicated.
A cell with no nucleus is a
prokaryote.
Bacteria
is a single-celled organism that do not have nuclei.
Prokaryotes
do NOT have a nuclei.
Common shapes of bacteria are:
cocci, spirilla, and bacilli.
Archaebacteria
can live in hostile environments.
Cyanobacteria
cotain chlorophyll.
Bacteria cells
have a loop of DNA.
Flagella
help the bacteria move around.
Flagellum
in Latin means whip.
Bacteriam are able to survive boilind, freezing, adn extremely dry environments by
becoming an endospore.
Prokaryotes
use cellular respiration, move around, and reproduce.
Methan makers live in
swamps.
The first plants
may have developed from cyanobacteria.
Bacilli
are rod shapped bacteria.
Cyanobacteria live in
water environments.
Heat lovers live in
ocean rift vents.
Salt lovers can be found in
the Dead Sea.
The three main types of archaebacteria are:
methane makers, heat lovers, and salt lovers.
Eubacteria that make their own food are
producers.
Decomposers feed on
dead organic matter.
Parasites
invade the body of another oranism to obtain food.
Decomposers, consumers, and parasites
obtain nutrients from other organisms.
The Eubacteria Kingdom
has more individual organisms than any of the other five kingdoms.
Spiral-shaped
is the least common shape for bacteriaum.
Bacilli
are bacteria the are rod-shaped.
Cocci
are spherical bacteria.
An endospore is
a thick protective membrane that contains an inactive bacterium.
Producers
make their own food.
Most bacteria reproduce by
binary fission.
