Content: Green
 
Algae
 
are
 
multicellular,
 
photosynthetic
 
protists,
 
but
 
lack
 
many
 
of
 
the
 
adaptations
 
that
 
plants
 
have
 
for
 
living
 
on
 
dry
 
land. Using
 
the
 
cladogram
 
in
 
Figure
 
1
 
as
 
a
 
guide,
 
we
 
see
 
5
 
traits
 
that
 
bryophytes
 
possess,
 
but
 
green
 
algae
 
lack. These
 
include,
 
an
 
alternation
 
of
 
generations
 
lifecycle,
 
apical
 
cell
 
division,
 
a
 
waxy
 
cuticle,
 
and
 
multicellular
 
gamete
 
producing
 
structures
 
(antheridia
 
and
 
archegonia). What
 
advantage
 
does
 
a
 
waxy
 
cuticle
 
give
 
to
 
a
 
land
 
plant
 
that
 
a
 
green
 
algae
 
lacks? What
 
advantage(s)
 
does
 
multicellular
 
gametangia
 
give
 
to
 
a
 
land
 
plant
 
that
 
a
 
green
 
algae
 
lacks? Using
 
the
 
cladogram
 
in
 
Figure
 
1
 
as
 
a
 
guide,
 
which
 
structures
 
do
 
bryophytes
 
lack
 
that
 
all
 
other
 
plants
 
(ferns
 
and
 
seed
 
plants)
 
possess? List
 
at
 
least
 
three. The
 
photosynthetic
 
portion
 
of
 
a
 
bryophyte
 
is
 
called
 
a
 
thallus. Remember,
 
bryophytes
 
lack
 
vascular
 
tissue,
 
so
 
they
 
do
 
not
 
possess
 
true
 
leaves,
 
roots,
 
or
 
stems
 
like
 
vascular
 
plants. The
 
life
 
cycle
 
of
 
bryophytes
 
is
 
characterized
 
by
 
distinct
 
alternation
 
of
 
generations
 
in
 
which
 
the
 
gametophyte
 
is
 
the
 
dominant
 
stage
 
of
 
the
 
life
 
cycle.
