Plant Phyla
Bryophyta
Filicinophyta
Coniferophyta
Angiospermophyta
Various terms
Rhizoids but no true
Vegetative organs-parts
of the plant concerned roots. Some with simple
with growth rather than stems & leaves; others
reproduction
have only a thallus
Vascular tissue- tissues
with tubular structures
used for transport
within the plant
Cambium- cells between
xylem and phloem that
can produce more of
these tissues
Pollen- small structures
containing male
gametes that are
dispersed
Ovules- contains a
female gamete &
develops into a seed
after fertilization
Seeds-dispersible unit
consisting of an embryo
plant and food reserves,
inside a seed coat
Fruits- seeds together
with a fruit wall
developed from the
ovary wall
Roots, stems, & leaves are usually present
No xylem or
phloem
Xylem and Phloem are both present
No cambium, no true trees &
shrubs
Present in conifers & most angiosperms,
allowing secondary thickening of stems & roots
& development of plants into trees & shrubs
Pollen is not produced
Pollen is produced Pollen is produced by
in male cones
anthers in flowers
No ovaries or ovules
No seeds
Ovules are produced
in female cones
Ovules are enclosed
inside ovaries in flowers
Seeds are produced and dispersed
No fruits
Fruits produced for
dispersal of seeds
