One
morning
in
mid-September,
I
was
surprised
to
see
my
favourite
tree
had
half
dozen
yellow
leaves
scattered
amongst
its
foliage.
With
the
beautiful
weather
we
had
this
summer,
the
change
in
the
leaves
is
following
a
more
leisurely
schedule;
some
years
Mother
Nature
seems
to
change
into
her
fall
suit
overnight.
Anyone
who
has
taken
a
course
in
Biology
knows
that
it
is
within
the
chloroplasts
found
in
leaf
cells
that
photosynthesis
takes
place
More
importantly,
it
is
in
the
chloroplast
thatthe
green
pigment.chlorophyll
is
found
in
abundance.
As
well
as
being
involved
in
the
initial
photosynthetic
reaction,
chlorophyll
is
what
gives
a
leaf
its
green
color
Yet
in
the
autumn,
birch
and
poplar
leaves
turn
yellow,
while
oak
and
maple
leaves
turn
to
various
shades
of
red
What
happens
within
the
leaf
to
allow
this
color
change
to
take
place?
The
first
change
involves
T
something
called
carotenoids,
which
are
also
found
within
the
chloroplast
Carotenoids'
yellow
pigment
is
masked
during
the
summer
months
by
the
overwhelming
numbers
of
chlorophyll
present
in
the
leaf.
With
the
cooler
weather
and
shorter
days
of
autumn,
chlorophyll
numbers
go
down
and
the
leaves
turn
yellow.
What
happens
within
the
leaf
to
allow
this
color
change
to
take
place?
The
oak
and
maple
leaf's
red
and
purple
colors
are
due
to
water
soluble
pigments
called
antho-cyanins
and
flavones,
which
most
trees
do
not
produce
until
autumn
With
cooler
temperatures,
the
transport
of
sugars
out
of
the
leaves
is
reduced
In
some
trees,
these
excessive
sugar
levels
are
used
to
form
anthocyanins,
producing
the
vivid
red
leaves
of
the
Scarlet
Oak,
or
the
dull
red
of
a
Douglas
Maple
The
various
shades
are
determined
by
the
amount
of
color
pigment
present
in
the
leaf
Nature
really
is
incredible'

You

also
access
the

from
the
site.
You
can
check
the
availability
of
a
book,
put
a
hold
on
it,
or
renew
one
you
keep
forgetting
to
return.
The
library
will
even
bring
in
a
book
from
other
libraries
for
you,
and
you
do
not
even
have
to
get
off
your
computer
chair.
Coming

to
the

is
access
to
exam
schedules,
the
ability
to
search
for
courses,
view

and
register

The
CNC

can
provide
you
with
the

is
great
if

Jason
Spenrath,
the
CNC
webmaster,
has
done
a
good
job
making
the
site
pretty
straightforward
and
easy
to
get
around
in.
My
only
criticisms
are
that
sometimes
I
find
it
is
too
easy,
and
there
is
almost
too
much
content,
and
I
often
find
myself
off
in
Kathy
Plett's
badfadscom
link
instead
of
doing
my
research.

Your
guess
is
as
good
as
mine
as
to
how
soon
"soon"
is,
but
I
can't
wait
to
kiss
that
long

up
goodbye.
