Transcript PLANTS MOVE TO LAND

PLANTS WITHOUT SEEDS
NON VASCULAR
2 TYPES OF PLANTS
 NONVASCULAR:
 plants that DO NOT have tubes that
carry water and food throughout the plant
 VASCULAR PLANT:
 plants that DO have tubes to carry food
and water throughout the plant
NEEDED FOR PLANTS TO
MOVE TO LAND
 Need to support the leaves and rest
of the body so that they do not
collapse
 What would help support the plant?
 Stems
NEEDED FOR PLANTS TO
MOVE TO LAND
 Need to obtain water and food.
 What helped the plant to get food and
water?
 Roots, Leaves
NEEDED FOR PLANTS TO
MOVE TO LAND
 Need to transport
water and food to
all different parts
of the body.
 What helped the
plant to get food
and water to all
parts of the body?
 Vascular tissue(
xylem, phloem)
NEEDED FOR PLANTS TO
MOVE TO LAND
 Need to prevent
excess water loss to
the environment.
 What helped the
plant to lose less
water?
 Cuticle: waxy
covering
1st PLANTS TO HIT LAND
 MOSSES
 LIVERWORTS
 HORNWORTS
MOSSES, LIVERWORTS &
HORNWORTS
 Adapted to land by:
 Living in places with a lot of water
 Remaining small in size
 They are Nonvascular
 Uses for humans:
 Decoration (in gardens)
 Soil conditioner
 Fuel (dried peat moss)
Importance of Non Vascular
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.

HORNWORTS
PLANTS WITHOUT SEEDS
VASCULAR
Characteristics of Vascular
Plants
 They can grow much taller than mosses
and hornworts
 They have true leaves, stems and roots
 Have a waxy coating on their leaves to
prevent water loss
 Reproduce by spores
Two types of vascular tissue
 XYLEM: carries
water and minerals
throughout the
plant
 Only goes in 1
direction….UP
XYLEM
Two types of vascular tissue
 PHLOEM: carries
food throughout the
plant
 Goes in both
directions
PHLOEM
Types of seedless vascular
plants
 Whisk Ferns: can
be found in
swamplands and dry
rocky cliffs
 Rhizomes: horizontal
stem of a plant that
is usually found
underground
Types of seedless vascular
plants
 Club Mosses: small,
creeping,
terrestrial plants
Types of seedless vascular
plants
 Horsetails: they are
erect, jointed,
brittle and grooved,
hollow except at the
joints
Types of seedless vascular
plants
 Ferns: have true
leaves but lack
flowers and seeds
 Fronds: part of fern
leaf that has the
spores
 Fiddleheads
Parts of Ferns
 Fronds: part of fern
leaf that has the
spores
Parts of Ferns
 Fiddleheads:
uncurled baby ferns
Reproduction in plants without
seeds
 Alteration of Generation: sporophyte
(produces spores) turn into a
gametophyte (produces a new plant)
 Sexual reproduction that requires
water for the sperm to reach the egg
Helpful effects of Ferns
 Popular houseplants
 Products from fern are used to grow
other plants
 Used in crop to house a bacteria that
acts as a fertilizer
 Some ferns can be eaten as food
