The classification of living things
Groups of living things with similar cells are called
kingdoms. There are five kingdoms: Monera, Protoctist,
Fungi, Plant and Animal.
The classification of living things
How are living things classified?
The Monera, Protoctista and Fungi Kingdoms
What is the Monera kingdom?
Monerans are simple unicellular
organisms. They don’t have bodies.
Monerans are microscopic, but not
all share the same characteristics.
The shape of the cell varies according to the type of organism. Some
monerans produce a substance that breaks down plant or animal
matter: they are heterotrophs. Moneras reproduce by division.
The Monera, Protista and Fungi kingdoms
What is the Fungi kingdom?
Most fungi are multicellular organisms, like
mould, but some are unicellular, like yeast.
Fungi produce spores that are carried by
the wind.
Many multicellular fungi consist of a cap, a
stem and a network of hyphae, long tubular
structures.
The Monera, Protista and Fungi kingdoms
What is the Protista kingdom?
Protists can be unicellular or
multicellular.
Algae contain chlorophyll and carry
out photosynthesis to produce food.
They are autotrophs.
Protists reproduce in two ways. Some produce spores. Algae
cells divide into two.
Plant kingdom
Seed plants Non-seed plants
Plants can be classifies into two main groups.
How can we classify plants?
Plant kingdomWhat are seed plants?
Seed plants reproduce by creating seeds.
There are two main types of seed plant: angiosperms
and gymnosperms.
Plant kingdomWhat are seed plants?
Angiosperms
They are also called flowering
plants. Fruit grows from the
pollinated flowers and the seeds
grow inside the fruit.
Plant kingdomWhat are seed plants?
Gymnosperms
The largest group is called
conifers. The seeds grow inside
the cones. Some conifer seeds
are called nuts.
Plant kingdomWhat are non-seed plants?
Some plants, such as ferns and mosses, don’t have seeds.
They produce special cells called spores. When spores
fall to the ground, they grow into new plants.
Plant kingdomWhat are non-seed plants?
Ferns
They have special leaves called
fronds. Spore capsules grow on
the fronds. Ferns are anchored to
the ground by their roots.
Plant kingdomWhat are non-seed plants?
Mosses
They produce capsules. Mosses
don’t have roots. They are anchored
to the ground by rhizoids.
The classification of invertebrates
How do we classify invertebrate animals?
Invertebrate animals are classified into six groups: arthropods,
molluscs, porifera, coelenterates, echinoderms and annelids.
The classification of invertebrates
Porifera
These invertebrates have a soft body
with holes called pores. They absorb
oxygen and nutrients through the pores.
They reproduce by forming a bud, or
small body part.
The classification of invertebrates
Molluscs
These invertebrates have soft bodies, and most also have a
hard shell. They absorb oxygen through gills, and reproduce
by laying eggs.
The classification of invertebrates
Cnidarians
These invertebrates have soft
bodies, and most also have a hard
shell. They absorb oxygen through
their skin, and reproduce by buds.
The classification of invertebrates
Arthropods
These invertebrates have an
exoskeleton and jointed legs that
bend. Most arthropods use trachea to
breathe, some have simple lungs, and
others absorb oxygen through their
gills. Arthropods are oviparous.
The classification of invertebrates
Annelids
These animals have a long, soft body
that is divided into rings called
segments. Some annelids absorb oxygen
through their skin, but others have
gills. Annelids can reproduce by
budding, but some are oviparous.
The classification of invertebrates
Echinoderms
Some of these animals have bodies
covered with sharp spines. Some
echinoderms have gills: others absorb
oxygen through their skin. Echinoderms
are oviparous.
The classification of invertebrates
What different types of body coverings do invertebrates have?
Hard shell Exoskeleton Soft body
Vertebrates: mammals and reptiles
What are the characteristics of mammals?
All mammals have lungs to breathe.
Mammals have skin and hair. Most mammals have four legs.
Almost all mammals are viviparous.
Vertebrates: mammals and reptiles
What are the characteristics of reptiles?
Reptiles have hard scales.
Reptiles have lungs to breathe.
Many reptiles have four legs, but snakes
don’t have legs.
Reptiles are oviparous.

Vertebrates: fish, amphibians and birds
What are the characteristics of fish?
Fish breathe with their gills.
They have a long body covered with scales.
Fish have fins and tails.
Almost all fish are oviparous.
Vertebrates: fish, amphibians and birds
What are the characteristics of birds?
Birds have lungs and four extremities:
two wings and two legs.
Birds have feathers over their bodies.
Birds are oviparous.
Vertebrates: fish, amphibians and birds
What are the characteristics of amphibians?
Amphibians have thin, smooth skin and
they have four legs.
When they’re young, they have gills to
breathe. When they become adults,
they grow lungs to breathe.
Amphibians are oviparous.
