I can list features that
can be used to classify
the five groups of
living beings
• There are millions of species on our planet. It would be difficult if we just tried to describe and name each one individually. Although species can be very different from each other, many of them have similar features that allow us to put them into groups.
• Putting different species into different groups according to their features is
called classification.
Why do we classify organisms? Why do we classify organisms?
Scientists across the world all use and recognise the same classification system.
In this classification system they start off using very big groups that include a lot of animals, and then move down to smaller groups that do not include as many animals.
The biggest groups are called the KINGDOMS. All living things are classified into five different kingdoms.
The Classification SystemThe Classification System
Organisms
Animals
Plants
Monerans
Protists
Fungi
Jellyfish, worms, arthropods, molluscs, echinoderms, amphibians, fish, reptiles, birds and mammals.
Seed bearing plants and non-seed bearing plants
Bacteria and cyanobacteria
Single-celled and multicellular organisms without tissues
Moulds, mushrooms and toadstools
Invertebrates
These animals do not have a backbone.
They have soft inner
bodies which are held in shape by a flexible
covering of outer cells or by a hard covering called
an exoskeleton.

Vertebrates
These animals have a backbone.
They have a firmer body because of the muscles that connect to their skeleton.

Animals
Invertebrates
•Hollow bodied
•Mouth is the only body
opening and is surrounded by
tentacles
•Uses sting cells to paralyse
prey
CnidariansCnidarians
Invertebrates
•Flat thin bodies
•Digestive system has
only one opening
•Animals are both male
and females
•Mostly parasites
FlatwormsFlatworms

•Bodies made of segments
True wormsTrue worms
Invertebrates
•Not segmented
•Body in three continuous
parts with head, body and
foot
•Have one or two shells
MolluscsMolluscs
