Living and Changing I can list features that can be used to classify the five groups of living beings

Why do we classify organisms? 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.

The Classification System 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.

Jellyfish, worms, arthropods, molluscs, echinoderms, amphibians, fish, reptiles, birds and mammals. Animals Seed bearing plants and non-seed bearing plants Plants Organisms Monerans Bacteria and cyanobacteria Protists Single-celled and multicellular organisms without tissues Fungi Moulds, mushrooms and toadstools

These animals do not have a backbone. Vertebrates These animals have a backbone. They have a firmer body because of the muscles that connect to their skeleton. 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.

Fish Live in water Breathe with gills Streamlined bodies Have cartilage or bony skeleton Cold blooded Mostly lay eggs

Amphibians Moist skin Lay their eggs in water Larvae have gills and live in water Adults have lungs and live on land Cold blooded

Reptiles Have dry, scaly skins Egg laying Breathe with lungs Cold blooded

Birds Have feathers and wings Lay eggs with hard shells Breathe with lungs Warm blooded Presentation to take 5mins

Mammals Have body hair or fur Have mammary glands that produce milk Warm blooded

Cnidarians Hollow bodied Invertebrates Hollow bodied Mouth is the only body opening and is surrounded by tentacles Uses sting cells to paralyse prey

Flatworms Flat thin bodies Digestive system has only one opening Invertebrates Flat thin bodies Digestive system has only one opening Animals are both male and females Mostly parasites

True worms Invertebrates Rounded bodied Bodies made of segments

Molluscs Not segmented Invertebrates Not segmented Body in three continuous parts with head, body and foot Have one or two shells

Echinoderms Spiny skinned Body in five parts Central mouth with gills Invertebrates Spiny skinned Body in five parts Central mouth with gills

Centipedes & Millipedes Arthropods Invertebrates Hard exo-skeleton on outside of body Has eyes and mouth Body divided into more than one segment Centipedes & Millipedes Crustaceans Arachnids Insects Presntation to take 10mins
