Classification of Plants and
Animals
Science Study Guide
What is classification?
•The process of grouping similar things
together.
How is it useful to scientists?
•Helps classify plants
and animals in
manageable way.
•Grouping living things
by similarities and
differences.
How do you classify organisms?
•Kingdom
•Phyla
•Class
•Order
•Family
•Genus
•Species
Remember: Kids Prefer Candy Over Fancy Green Salads
How do scientists group
organisms?
•Grouping organisms
by features they
share.
•Shape
•Size
•Body parts
•Color
What are the five kingdoms of living
things?
•Animals
•Plants
•Bacteria
•Fungi
•Protists
What is the main difference
between members of the plant
kingdom and members of animal
kingdom?
•Plants make their own food
•Animals eat other living things
What are the characteristics of
living things?
•Breath (oxygen or carbon dioxide)
•Eat (makes own food or eats other living things)
•Reproduce
•Grow
•Change
•Live (habitat)
How are animals classified into
groups?
•The largest way
animals are broken
into groups is
based on whether
they have
backbones or have
no backbone.
What are animals with backbones
called?
•Vertebrates (with a backbone)
•This group includes:
•Fish
•Amphibians
•Reptiles
•Birds
•Mammals
What are the characteristics of fish?
•Vertebrates
•Cold-blooded
•Have gills and scales
•Live in water
What are the characteristics of
reptiles?
•Vertebrates
•Cold-blooded
•Have scales
•Live on land
•Usually lay eggs
What are the characteristics of
amphibians?
•Vertebrates
•Live in or around
water
•Cold-blooded
•Have smooth skin
(must be kept
moist)
•Lay eggs
What are the characteristics of
birds?
•Vertebrates
•Have hollow bones
•Have feathers
•Warm-blooded
•Most can fly
•Lay eggs
•Have beaks
What are the characteristics of
mammals?
•Vertebrates
•Have fur or hair
•Warm-blooded
•Feed milk to their
young
•Bear live young
(except platypus’-
lay eggs)
What are animals without
backbones called?
•Invertebrates (without a
backbone
•This group includes:
•Sponges
•Anemones
•Jellyfish
•Worms
•Snails
•Sea stars
•Mollusks
•Urchins
•Insects
•Spiders
•Ticks
•Lobsters
•Crabs
•Crayfish
What are invertebrates?
Without a backbone!
Classification of Plants
How are plants classified into
groups?
•Plants have
characteristics that
are similar and
different too.
•Two major types of
plants:
•Vascular
•Nonvascular
What are vascular plants?
•Plants that have
tiny ‘tubes’ that run
between the roots
and leaves.
•Examples:
•Trees
•Ferns
•Grass
Pictures of magnified vascular
plants?
Enlarged picture of ash
wood tree. Notice long
vascular tubing.
Major vascular vein in
Zinnia leaf. Coiled
tubing.
More pictures of vascular plants.
Magnified horizontal view (400x). The strands consist of
tubes with spirally thickened walls that appear like
minute coiled springs.
What are nonvascular plants?
•Plants that do not
have tissue that
carries water from
root to leaf.
•Examples:
•Mosses
•Liverworts
•Hornworts
Picture of nonvascular plant.
A small mushroom emerging from a clump of mosses and
liverworts on a shady, moist bank in southern California.
Classification Review
•Plants and Animals are ‘multi-celled’
organisms.
•7 ways to classify all living things
•Kingdom, phylum, class, order, family, genus,
species
•5 Kingdoms are:
•Animals, Plants, Bacteria, Fungi, and Protists
