Plants
Nonvascular
Vascular
Angiosperms
Monocots
Dicots
Gymnosperms
NONVASCULAR PLANTS
Early Plants
have no vessels, no roots, no stems or
leaves. Examples: Mosses & Liverworts
VASCULAR PLANTS
Modern Plants
have vessels to transport food and water. They
have roots, stems and leaves. Most reproduce
by seeds. Example: Grass, corn, trees, flowers,
bushes
GYMNOSPERMS
 "naked seeds"
 cone bearing (seeds
grow on cones)
 needle like leaves
 usually stay green
year round
 wind pollinated
 Examples: pine trees
& evergreens
ANGIOSPERMS
 flowering plants
 Seeds enclosed in a fruit
 most pollinated by birds
& bees
 have finite growing
seasons
 Examples: grasses,
tulips, oaks, dandelions
 Divided into two main
groups: Monocots &
Dicots
Ex. Lilies, onions, & corn
Ex. Trees & ornamental flowers
Parts of the Plant
Foldable Instructions
 Fold a WHITE
piece of paper in
half
 On the cover draw
a flower (include
flower, stem,
leaves, and roots)
After drawing the flower,
cut the drawing in 3
sections (flaps)
 one for the flower
 one for the stem and
leaves
 and one for the roots
 Then under each
flap you will be
writing the
corresponding
information for
each part.
Flower
 Reproductive organ of the plant
 Flowers are usually both male and female
 PETAL: Leaf like flower organs, usually brightly colored.
 STAMEN: Male reproductive organ of a flower consisting of an
anther and a filament.
 ANTHER: Pollen producing structure located at the tip of a
flower’s stamen.
 PISTIL: Female reproductive organ of a flower

Stems – complete on foldable
 Organ that provides support and growth; transport
water through xylem and nutrients through phloem;
organ from which leaves grow, can serve as storage.
 Two types of stems: herbacious and woody
 Xylem: vascular plant tissue made up of tubular cells
that transport water and dissolve minerals from roots to
the rest of the plant
 Phloem: Vascular plant tissue made up of tubular cells
joined end to end; transport sugars to all parts of the
plant.
Leaves – complete on foldable
 Photosynthetic organ of the plant, used to convert
sunlight into food
 Photosynthesis Equation:
Parts
Stomata: pores that let CO2 in and O2 out.
Cuticle: waxy layer on upper surface that protects
against water loss.
Veins: transports water, nutrients and food. Made of
xylem and phloem.
