Mosses and Liverworts
Small
Live on bark, rocks,
and soil
No vascular
system
Must live in places
that are wet
No true roots,
stems, or leaves

Mosses and Liverworts
Live together in large groups
Covering soil or rocks in a mat of
tiny green plants
Each moss has rhizoids (root-
like structures)
Rhizoids help anchor the plant
Reproduce by spores

Importance of Mosses and
Liverworts:
Pioneer plants - usually the first
plants to inhabit a new environment.
Form a thin layer of soil when they
die.
They help hold the soil in place
which prevents erosion.
Nesting material for birds.
Peat moss can be burned as fuel.

Ferns, Horsetails, and
Club Mosses:
Grow tall
Have vascular
systems
Reproduce by
spores

Ferns
Can grow almost
anywhere.
Have an
underground stem
called a rhizome.
Leaves are called
fronds.

Horsetails

Horsetails
Small vascular plants.
Grow less than 1.3 meters tall.
Grow in wet, marshy places.
Stems are hollow and contain
cilia.
Pioneers used them to scrub
pots and pans.

Club Mosses
25 cm tall.
Grow in woodlands.
Unlike other mosses, they have vascular tissue.

Importance of Seedless
Vascular Plants
Help form soil when they die.
Also hold soil in place to prevent erosion.
Ferns serve as house plants.
Some are cooked and eaten.
Formed coal.
Used as folk medicine
