and
reproduce
;
they
take
in
____________________
,
water
,
food
and
get
rid
of
____________________
;
they
____________________
to
their
environment
;
and
all
living
things
are
made
of
____________________
.
Living
things
,
also
called
____________________
,
that
are
made
of
only
one
cell
are
____________________
organisms
.
Living
things
that
are
made
of
many
cells
working
together
are
____________________
organisms
.
Cells
make
up
the
____________________
of
organisms
.
This
means
that
they
make
up
the
body
parts
of
living
things
.
Cells
do
the
____________________
of
organisms
.
This
means
that
they
do
the
____________________
that
keep
an
organism
alive
like
exchanging
oxygen
and
carbon
dioxide
,
taking
in
food
,
and
making
energy
.
Cells
are
____________________
,
meaning
that
they
are
too
small
to
see
with
the
human
eye
.
Scientists
need
____________________
to
see
cells
.
The
invention
of
the
____________________
helped
scientists
discover
that
all
living
things
are
made
out
of
____________________
.
The
____________________
of
a
microscope
is
where
you
look
through
.
The
____________________
holds
the
specimen
on
the
stage
,
and
a
____________________
shines
up
and
through
.
You
can
adjust
the
focus
with
the
focusing

.
____________________
make
the
cells
appear
larger
.
____________________
power
lenses
make
the
specimen
under
the
microscope
a
little
bit
bigger
,
and
without
a
lot
of
detail
.
____________________
power
lenses
make
the
specimen
much
bigger
and
show
much
more
____________________
.
The
____________________
theory
has
three
parts
:
1
-
all
living
things
are
made
of
____________________
.
2
-
cells
make
up
the
____________________
and
____________________
of
living
things
.
3
-
____________________
cells
must
come
from
____________________
(
pre

existing
)
cells
.
