Below
you
are
given
graphs
that
show
the
ability
of
various
solutions
to
absorb
 light
at
different
wavelengths.


 
 
 In
the
above
figure,
what
colors
are
least
absorbed
by
this
particular
pigment?

What
 color
is
the
most
absorbed?
 
 
 
 
 Given
the
graph
above,
what
color
would
you
perceive
the
solution
to
be?

What
 color
of
light
is
absorbed
least
by
this
pigment?

What
color
of
light
is
absorbed
most
 by
this
pigment?
 
 
 
 
 2.

In
the
space
provided
on
the
next
page,
please
draw
your
chromatography
 results,
and
label
each
of
the
pigments.

Why
did
the
pigment
that
was
the
closest
to
 the
top
travel
so
much
faster
than
the
ones
closer
to
the
bottom?

Please
hypothesize
the
results
you
would
expect
to
see
in
each
of
the
following
 situations,
and
please
explain
Why.
 
 A)

A
plant
is
kept
in
a
greenhouse
where
it
is
given
light
twenty‐four
hours
a
day.

 The
leaf
is
boiled
in
ethanol,
placed
in
water,
and
then
place
in
iodine.
 
 
 B)
A
plant
is
kept
in
a
greenhouse
that
is
illuminated
for
six
hours
a
day
and
kept
in
 complete
darkness
for
eighteen
hours
a
day.

Ten
hours
into
the
darkness
cycle
of
 the
greenhouse,
the
leaf
is
plucked,
boiled
in
ethanol,
placed
in
water,
and
then
 placed
in
iodine.
 
 
 
 
 
 
 
 
 C)

A
plant
is
placed
in
a
windowless
room
for
a
week
with
no
sources
of
light
 anywhere.

A
leaf
is
plucked
from
this
plant
and
boiled
in
ethanol,
placed
in
water,
 and
then
