Seedless Nonvascular
Plants
rhizoids- threadlike
structures that
anchor nonvascular
plants to the ground
Mosses
Liverworts
Hornworts
Mosses
 Grow on tree trunks,
rocks, or ground
 Commonly in damp
areas
 Multi-celled rhizoids
Lab- Measuring Water
Absorption by a Moss
1. Place a few teaspoons of Spagnum
moss on a piece of cheesecloth.
2. Gather the corners of the cloth and
twist, then tie them securely to form a
ball.
3. Weigh the ball.
4. Put 200 mL of water in a container and
add the ball.
5. Wait 15 minutes.
Liverwort
 Flattened, leaflike
bodies
 One-celled rhizoids
Hornworts
 Flattened body (like
liverwort)
 Spore-producing
structure (look like
horns)
Summarizing
Seedless Nonvascular Plants
 Include mosses,
liverworts, hornworts
 Only a few cells thick
(each cell absorbs
water directly from its
environment)
 No more than a few
centimeters tall
 Produce spores rather
than seeds
 Are considered pioneer
species- 1st to grow in
new area

Finish Lab
1. Remove the ball and drain the excess
water into the container.
2. Weigh the ball and measure the amount
of water left in the container.
(Remember you started with 200 mL.)
3. Record your results.
4. Clean up your lab area.
5. Wash your hand.
Seedless Vascular Plants
 Also produce spores
instead of seeds
 Have tubelike structures
(bigger and thicker than
nonvascular)
 Can live further away
from water

Seedless Vascular Plants
Characteristics
Types
Ferns
 Largest group
 Fern leaves are
called fronds
Club Mosses
 A.K.A.
ground pines
spike mosses
 Needle like leaves
 Spores look like tiny
pine cones
Horsetails
 Stem is jointed with
hollow center
 Pops apart in
sections
 Conelike at tips
 Used for:
polishing objects
sharpening tools
scouring utensils
Importance of Seedless
Plants
 Nonvascular help
build new soil
 Houseplants and
landscaping
 Peat-forms from
remains of
sphagnum moss
 Mined from bogs
 Used as a low-cost
fuel
