-Active
transport
- Vascular
tissue
(xylem
conducts H2O
and phloem
conducts
dissolved
nutrients)
- Small roots
-Rhizoids (no
true roots)
- See p. 435
- Leafy
appendages
- No true leaves
- Asexual
(fragmentation)
or sexual (see
below)
- Alternation of
generations life
cycle involving
haploid
gametophytes
and diploid
sporophytes
- See p. 436
(fig. 13.33)
- Pioneer plants
and soil builders
which lead to
succession
-Eastern spruce
-White pine
-Douglas fir
-Western red
cedar
-Juniper
-Ginkgo
- Vascular
tissue
-Rose
-Crab apple

spreading roots
- Spreading
roots
- Leaves
- Needles
(leaves)
- A variety of
leaves
- Sexual
- Produce
spores instead
of seeds
- Alternation of
generations life
cycle involving
haploid
gametophytes
and diploid
sporophytes
- See p. 438
(fig. 13.36)
- Primary
producers that
contribute to
soil building and
create a
habitat and
food for other
species
- Sexual
- Produce seeds
in scales of
female seed
cones that are
fertilized by
pollen from male
pollen-producing
cones
- See p. 439
(fig. 13.38)
- Sexual
- Produce seeds
in the ovary of
the flower
- The ovary
becomes the
fruit
- See p. 441
(fig. 13.42)
- Primary
producers that
provide food,
shelter and
oxygen for
other species
- Building
materials
- Primary
producers that
provide a wide
variety of
habitats and
food for other
species
- Vascular
