Kingdoms of
Life
Classification of
Living Organisms
What does it mean to classify?
Classification – to place items into a
group based on characteristics that they
have in common.
Carl Linnaeus

•1707 (how long ago was that)
•Father and grandfather
were Lutheran priests
•God created the world, so
studying the world was
studying God.
•Studied and became a
doctor.
•Wrote The System of Nature
•Became a professor
5 Kingdoms of Life
* Plant (
All organisms can be organized
into one of five kingdoms. This
system was developed by Carl
Linnaeus.
1. Animal
2. Plant
3. Fungi
4. Monera
5. Protist
Kingdom
Phylum
Class
Order
Family
Genus
Species
Variety
Animalia – an animal
Chordata – internal skeleton (spinal chord)
Mammalia – a mammal
Carnivora – carnivor
Canidae – dog like characteristics
Canis – coyote, wolves, dogs
Familiaris – domesticated
Collie – the specific breed
You can remember the subgroups
of each kingdom with this
acronym…
King = kingdom
Philip = phylum
Came = class
Over = order
For = family
Good = genus
Spaghetti = species
Taxonomy – A system of
classifying living things, that
gets increasingly more
specific.
The genus and species of a human is:
Homo – man (human)
sapien –wise
Kingdom Monera
What is a moneran?
Moneran
– an organism
without a membranebound nucleus; also
known as a prokaryote;
most monerans have only
1 cell.
What is an example of a moneran?
Bacteria
Kingdom Protista
Review:
What is a protist?
Protist – an organism that is
typically one cell that has a
membrane bound nucleus.

Examples of protists:
Algae
Amoeba
Euglena
Protozoan
Diatoms
Protista
Algae: a group of protists that
can make their own food
through photosynthesis. GREEN
Protista
Euglena: a tiny single-celled
organism; often classified as
algae
Protista
Why can we see algae?

Algal cells form
together in cell
colonies.

A single colony can
consist of up to 500
cells each with a pair
of flagella for
movement.

The colony works
together and moves
as one unit.
Cell Colony – groups of identical cells.
Protista
Amoeba: a one-celled organism that
moves by continually changing shape;
can only be seen with a microscope.
Fungus
Fungus
Fungi
Fungus
– a decomposing,
or parasitic organism that is
separated from the plant
kingdom because of the
way it gets nutrients.
Fungi
Examples
of fungi:
Mushrooms
Yeast
Mold
Mildew
Fungi - Mushrooms
Spore – a single reproductive cell
that when released can grow into a
new fungus.
Animalia
 Animal
– multi-celled organism that can move; able
to consume other organisms for food (food chain).
Animalia
Vertebrates – animals with a
backbone
Invertebrates – animals without a
backbone
invertebrates
Animal - Invertebrates
Invertebrates do not have an internal skeletal
systems. There are 6 groups of invertebrates: worms,
echinoderms, mollusks, arthropods, and cnidarians.
Look at the invertebrates in the following slides and
explain how…
#1 they survive without an internals skeleton
#2 benefits of living without a skeleton.
Think about (protection, getting food, survival, etc.)
vertebrates
Animal - Vertebrates
 Vertebrates
can be split into 5 groups based on
characteristics such as:
- Skin covering
- Warm blooded/cold blooded
- How they deliver offspring
- How they feed their babies
- How they breathe
The five classes of vertebrates are:
Mammals
MR. FAB
Reptiles
Fish
Amphibians
Birds
cold-blooded (internal body temperature
changes with the temperature of the
surroundings). Fish, amphibians, and
reptiles
warm-blooded (maintain a nearly
constant body temperature regardless of
the surrounding temperature).Birds and
mammals
Plant Kingdom – is a separate unit
