Introduction
  
Plants
 
are
 
multicellular
 
eukaryotic
 
organisms
 
that
 
are
 
autotrophic
 
(produce
 
their
 
own
 
food
 
by
 
photosynthesis),
 
and
 
possess: apical
 
cell
 
division,
 
chlorophyll,
 
a
 
waxy
 
cuticle,
 
and
 
have
 
cell
 
walls
 
containing
 
cellulose. Furthermore,
 
all
 
members
 
of
 
the
 
plant
 
kingdom
 
have
 
variations
 
of
 
a
 
life
 
cycle
 
described
 
as
 
alternation
 
of
 
generations. In
 
the
 
alternation
 
of
 
generations
 
life
 
cycle
 
there
 
are
 
two
 
mature
 
stages
 
known
 
as
 
the
 
sporophyte
 
and
 
gametophyte. The
 
sporophyte,
 
which
 
is
 
always
 
diploid
 
(2n),
 
produces
 
haploid
 
(n)
 
spores
 
by
 
the
 
process
 
of
 
meiosis
 
in
 
structures
 
called
 
sporangia. Spores
 
germinate
 
and
 
develop
 
into
 
gametophytes,
 
which
 
are
 
always
 
haploid. The
 
haploid
 
gametophyte
 
produces
 
gametes
 
(sperm
 
or
 
eggs)
 
which
 
later
 
fuse
 
to
 
form
 
a
 
diploid
 
zygote. The
 
zygote
 
develops
 
into
 
the
 
mature
 
sporophyte,
 
thus
 
completing
 
the
 
life
 
cycle. The
 
major
 
groups
 
of
 
plants
 
that
 
you
 
will
 
examine
 
in
 
this
 
week's
 
lab
 
exercises
 
are
 
bryophytes
 
(hornworts,
 
liverworts,
 
and
 
mosses)
 
and
 
ferns. Next
 
week
 
we
 
will
 
examine
 
the
 
Gymnosperms
 
("naked
 
seed"
 
producing
 
plants)
 
and
 
Angiosperms
 
(flowering
 
plants),
 
which
 
are
 
the
 
"most
 
advanced"
 
plants
 
alive
 
today.
