Classification of Living Things

What is classification?

It is the grouping of living organisms

according to similar characteristics.

A scientist called Aristotle grouped animals according to the way they moved

The modern classification system was developed by:

Carolus Linnaeus

The modern classification method consists of 7

levels: Kingdom Phylum Class Order Family Genus Species

Classification of humans:

The Animal kingdom is divided into 2 groups.

Vertebrates InvertebratesAnimals with a

backboneAnimals without a

backbone

Invertebrates include:

Snails

Mollusks(include many shelled

animals)

Echinoderms

Clams Sea urchin

Star fish

Invertebrates also include:

Spiders

Arthropods(Largest invertebrate phylum)

Crabs Insects

Lobster

Vertebrates include:

Mammals

Birds Fish Reptiles

Amphibians

Mammals

Hair or fur (to keep warm)

Ex. Polar bear

Lungs(to

breathe in

oxygen)Ex.

Whales

Give birth

to babies

. (Parents take care

of the baby,

until it can live alone)

Feed their

babies milk.

Birds

Feathers

Wings (to help them fly)Penguins

have wings

but cannot

fly.

Two legs

Lungs(to

breathe oxygen

from the air)

Lay eggs

Penguin

Crocodile

Scales

Reptiles

Dry skin

Skin is covered

with scales

(thin flat plates to protect the

animal)

Lungs(reptiles that spend lots of time in water

go to the surface to breathe oxygen)

Some lay eggs, some give

birth.

Eggs have tough, leathery shells.

Fish

Live their whole life in water

Gills

Skin covered

with scales

Most lay eggs, Some

give birth

Amphibians

Lay eggs in water

Moist skin

Young live in water. Adult live on land

Newt

Salamander Toads

Frogs

Plant kingdom can be classified as:

Vascular plants

Non-Vascular plants

Vascular plantsHave tubes or vessels

Phloem Xylem

Transports food Transports water

Vessels

Giant redwood trees.

Cactus.

Orchids

Non- Vascular plants

(without vessels)

Non vascular plants grow close to the ground to absorb water

Non-vascular plants

- They don’t have real roots. (They just look like roots)- They have parts that look like stems but they are not real stems.- They have leaf like structures, but they are not real leaves.

The leaves, stems and roots are not real BECAUSE:

They do not have VESSELS.

When non-vascular plants are dry they look like:

Dry sponge

Non-vascular plants are absorb water like:

sponges
