Kingdom Plantae
Multi-cellular
 Autotrophic
 Eukaryotic
 Cell walls made of cellulose
 Store food in the form of starch

 Have
chloroplasts containing
chlorophyll
 Most are terrestrial, some are
aquatic
Prepare a table to compare
Nonvascular and Vascular
Non-vascular
Vessels
(xylem and
phloem)
Leaves,
roots, stems
Examples
Vascular
Nonvascular
 No
vessels
 No roots
 No stems
 No leaves
 Ex: Mosses and
liverworts
Vascular
 Have
vessels to
transport food and
water
 They have roots,
stems and leaves
 Ex: grass, corn,
trees, flowers,
bushes
 Xylem:
transports water
 Phloem: transports food & nutrients
Vascular Plants can be sub-divided
into Seedless vs Seed Plants

Seedless plants (e.g., ferns) have a vascular
system but reproduce using spores.
Seed Plants can be further
subdivided into
Gymnosperms and Angiosperms
Gymnosperms
Type of

for seed

Type of
pollination
Examples
Angiosperms
Seed Plants
Gymnosperms
 Cone-bearing plants
 “naked seeds” = seeds that
are not enclosed.
 needle-like leaves
 usually stay green year
round
 wind pollinated
 Examples: pine trees & other
evergreens

Angiosperms
Flowering plants
Seeds are enclosed, usually in a
fruit
Have finite growing seasons
Most are pollinated by birds & bees
The most successful group of plants
Examples: grasses, tulips, oaks
Divided into two main groups:
Monocots & Dicots
Angiosperms can be further
subdivided into Monocots and
Dicots
Monocot
Number of
Cotyledons
Type of leaf
veins
Type of root
Arrangement
of vessels
Examples
Dicot
Monocots
1 seed leaf (cotyledon)
 parallel veins on leaves
 3 part symmetry for
flowers
 fibrous roots
 Vascular tissue
scattered
 Example: lilies, onions,
corn, grasses, wheat

Dicots
2 seed leaves
(cotyledons)
 net veins on leaves
 flowers have 4-5 parts
 taproots
 Vascular tissue arranged
in a ring
 Examples: trees and
ornamental flowers

Success of Angiosperms
Transport gametes over great distances.
 Efficient dispersal via fruit.
 Tough, water resistant leaves for survival
in hostile environments.

Pollination
Co-evolution between
flowers and
pollinators.
 Birds are attracted to
red flowers.
 Bees can see colors
that humans cannot.
 Moth-pollinated
flowers are white and
bloom at night.

Many insects are attracted to
odors. One species smells like
rotting meat and is pollinated by
flies.
 Flowers are often shaped so that
non-pollinators cannot reach
nectar or pollen. For example,
hummingbird-pollinated flowers
are long, and shaped like the bill
of a hummingbird.
 Wind-pollinated flowers are small,
have no petals and little color and
do not produce nectar.

Problems living in a terrestrial
ecosystem

Support - in water, the plant is held up.
On land, a support system is required.
Getting Water and Nutrients
Aquatic plants are surrounded by water and
nutrients so most cells can just absorb them the
environment. Terrestrial plants require a system for
collecting and transporting water.
 Plants developed root systems that can collect and
transport water. Some plants have shallow roots
which spread out to collect water.
 Water carrying minerals from the roots can travel
to all parts of the plant and food made in the
leaves can travel to non-photosynthetic parts of the
plant.

Drying Out
Leaves are covered by a
waterproof outer layer
called the cuticle.
 Openings in the leaves
called stomata allow
passage of gases for
photosynthesis but can be
closed when it is too
warm.
 Gymnosperms have very
narrow leaves to minimize
water loss.

Spreading Gametes
Spores – tiny reproductive cells are carried
long distance by the wind
 Seeds:

– The embryo inside the seed is surrounded by a
tough, drought-resistant, protective seed coat.
Food packaged in the seed provides energy for
the young plant until it can grow above the soil
and begin photosynthesizing.
– Adaptations of seeds help in their dispersal.
Some seeds are carried by wind, stick to the fur
of animals or are eaten.
Today’s Work
Complete the Monocot/Dicot colouring

YOU SHOULD BE VERY FAMILIAR WITH
THIS COLOURING FOR THE UNIT TEST!
