Download Plants with Seeds

Kingdom
Plantae
Characteristics
• Multicellular
Cells have a
cell wall
• Producers - make
their own food
• Have a cuticle
Waxy layer on
stems and leaves
keeps plants from
drying out
• 260,000 species
• 2 main groups
Vascular
Non-vascular
• Nonvascular
• no specialized tubes
to transport water,
nutrients and food
examples:
mosses and
liverworts
Mosses and Liverworts
• Seedless
• depend on osmosis
and diffusion
• plants are small
• live in wet
environments
Mosses and Liverworts
• live in wet environments
• rhizoids are root like
structures to anchor
plants
• important because they
are 1st plants to inhabit
a new, bare
environment.
II. Vascular
plants
• have specialized
tissues to
transport water,
nutrients
and food.
Seedless
•Ferns, horsetails,
and club mosses
Seeds
•Gymnosperms
•Angiosperms
Vascular Plants - No
seeds
• Ferns, horsetails,
club mosses
• Reproduce with
spores
Ferns
• Underground
stem - rhizome
• leaf is called a frond
• can be very large
• like moist
environments
Horsetails
• common millions
of years ago
• 15 species exist today
• less than 1.3 meters
tall
• look like a bushy
horses tail
Club Mosses
• 25 cm tall
• grow in woodlands
• common millions
of years ago
• 1000 species exist
today
Plants with Seeds
• Gymnosperms
trees and shrubs that
produce seeds in cones
naked seeds
Pines, spruce, fir &
ginkos
important for wood for
building and paper
products
Plants with Seeds
• Angiosperms
• (flowering plants)
produce seeds within
a fruit
fruit trees, roses, oak
trees, grasses, cactuses
235,000 species
Angiosperms
• Flowers attract
animals for
pollination
• Fruits protect and
house seeds for
survival
Monocots
• Flower petals
in 3’s
• leaves with
parallel veins
Monocots
• one cotyledon
• bundles of
vascular
tissue scattered
Dicots
• Flower petals
in 4’s or 5’s
• leaves with
branching veins
Dicots
• 2 cotyledons
• bundles of
vascular tissue
in a ring
Structures of
Seed Plants
• Stem
Supports plant
transport materials
• Xylem - transports
water and minerals up
• Phloem - transports
sugar molecules down
Roots
• Supply plants with
water & minerals
• anchor plant
• store surplus food
Leaves
• absorbs light
energy for
photosynthesis
• Carbon dioxide +
water = Glucose &
oxygen
