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.
