Bacteria
are
unicellular
,
meaning
they
have
only
1
cell
.
They
are
,
simpler
forms
of
life

They
have
no

They

They
are

Classifying
bacteria
by
their
cell
wall
is
done
by
Gram
stain
.
A
series
of
chemicals
are
put
on
it
to
see
what
sticks
.
Because
they

different

in

they

They
have

chemical
called
peptidoglycan

Gram
negative
bacteria
stain
.
They
have
cell
walls
with
a
peptidoglycan
layer
and
other
molecules

Antibiotics
won

t
work
on
because
they
have
no
cells
or
cell

!
Remember
that
can
work

too
,

We're
finding
our
medicines
aren

t
working
any
more
so
diseases
like
and
are
becoming
more
common
.
This
is
an
example
of
evolution
/
.
In
a
population
of
bacteria
,
some
have
a
/
variation
that
allows
them
to
not
be
affected
by
the
antibiotic
.
They
and
reproduce
more
with
that
resistance
(
NOT
"

)
.
So
our
drugs
won
?
t
work
on
those
anymore
.
Bacteria
like
this
are
called
.
This
can
happen
in
one
of
three
ways
.
is
when
antibiotics
are
used
when
not
necessary
,
like
when
someone
is
not
sick
or
is
sick
with
a
virus
.
:
is
when
people
don
?
t
take
all
the
medications
because
they
feel
better
.
This
basically
kills
the
weak
ones
and
lets
the
resistant
ones
survive
and
reproduce
.
happens
in
agriculture
when
farmers
give
antibiotics
to
healthy
animals
.
