Background
Information
Cells
are
living
organisms.
In
order
to
be
alive,
a
cell
must
have
a
metabolism,
respond
to
stimuli
and
reproduce.
Prokaryotes
Prokaryotes
are
simple
cells
that
do
not
contain
a
nucleus
or
other
membrane
bound
organelles.
The
major
parts
of
a
prokaryotic
cell
include:
cell
wall,
cell
membrane,
ribosomes,
and
a
nucleoid.
Even
with
a
minimal
number
of
parts,
these
cells
are
able
to
eat,
breathe
and
reproduce.
There
are
two
kingdoms
of
organisms
that
comprise
prokaryotes:
bacteria
and
archaea.
Bacteria
make
up
most
of
the
prokaryotes.
There
are
also
archaea,
which
are
found
in
extreme
environments
like
hot
springs
or
near
volcanoes.
The
difference
between
bacteria
and
archaea
is
their
type
of
cell
wall:
archaea
have
a
thicker
cell
wall
that
is
very
strong
and
protects
it
from
the
heat
and
chemicals
found
in
the
harsh
environments
they
live
in,
and
bacteria
have
a
more
permeable
cell
wall
that
provides
less
protection
from
high
temperatures
or
extreme
pH,
but
takes
less
energy
to
build.
Both
bacteria
and
archaea
are
unicellular
organisms.
Although
they
sometimes
live
in
colonies
each
cell
could
survive
on
its
own
and
reproduce
without
the
others.
Eukaryotes
Eukaryotes
are
complex
cells
with
many
organelles.
The
major
organelles
found
in
a
eukaryotic
cell
are:
cell
membrane,
cell
wall,
ribosomes,
nucleus,
mitochondria,
endoplasmic
reticulum
and
lysosomes.).
There
are
both
unicellular
and
multicellular
eukaryotes.
The
four
kingdoms
of
eukaryotic
organisms
are
plants,
animals,
fungi
and
protists.
Plants
are
photosynthetic
organisms
containing
cell
walls
and
specialized
reproductive
tissue.
Animals
are
organisms
which
lack
cell
walls,
but
are
capable
of
locomotion
and
have
a
digestive
tract.
Fungi
digest
their
food
externally
and
then
absorb
it
through
their
cell
walls.
Plants,
animals
and
fungi
are
all
multicellular
organisms.
Protists
are
single
celled
motile
organisms
that
can
be
either
photosynthetic
or
heterotrophic.
Eukaryotes
and
Prokaryotes
Similarities
There
are
some
similarities
between
prokaryotes
and
eukaryotes.
First,
they
both
have
cell
membranes
that
separate
the
cell
interior
from
the
outside
environment.
They
both
have
ribosomes
that
help
make
proteins
and
enzymes
for
metabolism.
Finally,
both
prokaryotes
and
eukaryotes
have
their
genetic
material
in
the
form
of
DNA.
Deoxyribonucleic
acid,
or
DNA,
contains
the
information
the
cell
needs
to
make
proteins
to
breakdown
food
into
energy
as
well
as
the
instructions
for
reproduction.
