The Plant Kingdom
4 This kingdom has organisms that are multi-
cellular, have cell walls and chlorophyll,
produce their own food, and don’t
physically move from one place to anotherz.

Non - flowering Plants
Do NOT produce flowers
A plant can be divided into 3 parts
Examples of Mosses
spores
Spore-producing capsule
.No true roots, No vascular tissues (no transport)
Characteristics of Mosses
.Simple stems & leaves
.Have rhizoids for anchorage
.Spores from capsules (wind-dispersal)
.Damp terrestrial land
.Simplest plants

Flowering
Plants
. roots, stems, leaves
. vascular tissues (transport)
. flowers, fruits (contain seeds)
Monocotyledons
Parallel veins
. one seed-leaf
Characteristics of Monocotyledons
leaves have parallel veins
. herbaceous plants
. e.g. grass, maize
Dicotyledons
Veins in network
. two seed-leaves
Characteristics of Dicotyledons
. leaves have veins in network
. e.g. trees, sunflower, rose
Non-Vascular
plants that do not have tubes to carry water
up the plant or tubes to carry food made in
the leaves down the plant
Examples:
– mosses
– liverworts
– ferns
– hornworts
Non-Vascular
Spore: the reproductive cell of a
nonvascular plant

The pistil consists of three parts: the stigma, style, and
The stigma is the sticky part that traps and holds the p
The style is the tube-like structure that holds up the sti
The ovary and the ovule are at the bottom of the style.

KEY CONCEPT
Plants can be classified into nine phyla/divisions.
Land plants are classified by the
presence or absence of vascular tissue
and how they reproduce (with or
without seeds)
“Vascular”
– People: relating to vessels, especially those that
carry blood.
– Plants: relating to plant tissues that conduct
water, sap, and nutrients.
Vascular Plants vs. Nonvascular
Plants
Vascular
Transport System
– Leaves
– True roots
– Xylem
– Phloem
– Stems
Can grow tall
Live in dry areas
Nonvascular
No Transport System
– No roots (rhizoids)
Grow close to the ground
to absorb water and
nutrients
Live in moist areas
