Classification of living organisms

The Kingdoms All living things are divided into 5 kingdoms: 1.Prokaryotes - Single celled organisms.

The Animal kingdom We will often focus on Invertebrates. Invertebrates make up 97% of all animal species (the other 3% are mammals, birds, fish, reptiles & amphibians). This means there are a lot of different species to identify! However, we can sort them into smaller groups called classes and then into orders.

The invertebrates we are likely to find fall into 6 classes: Crustaceans Arachnids Molluscs Worms Myriapods Insects Use the information cards to sort the invertebrates into their different classes.

Invertebrate Facts About 75% of all species described are invertebrates It is estimated that 10,000,000,000,000,000,000 (or ten million, million, million) individual invertebrates are on the planet at any one time. An average brood of Great Tit chicks will consume around 120,000 caterpillars whilst they are in the nest 1 in 3 mouthfuls of food contain insect pollinated products. Malaria kills one person every 12 seconds

The Plant kingdom We will often focus on Flowering Plants. These can be divided into two groups: *Those with a vascular system of phloem and xylem and true roots. * Those without - usually smaller plants with gaseous exchange across membranes and through pores and fibrous rhizoids rather than roots.

The Plant kingdom Vascular: * Ferns * Conifers * Flowering Plants Non-vascular * Mosses * Liverworts

Plant Facts 400,000 Plant species worldwide 20% of UK Flora is threatened Plants provide the photosynthetic pathways that capture sunlight energy for our food chains Plant science inform agriculture, conservation, horticulture and environmental issues.

The Classification System Kingdom - largest, most diverse Phylum Class Order Family Genus Species-smallest, least diverse Increasingly specific

Crustaceans Shell-like exoskeleton Variable number of body segments Antennae 14 legs No wings

Worms No exoskeleton Lots of body segments No antennae No legs No wings

Arachnids Exoskeleton 2 body segments No antennae 8 legs No wings

Molluscs No exoskeleton 1 Body segment Eyes on tentacles No legs No wings

Myriapods Exoskeleton Lots of body segments Antennae At least 14 legs No wings

Insects Exoskeleton 3 Body segments Antennae 6 legs 2 or 4 wings

We can divide the insects into smaller groups called orders: Butterflies & Moths (Lepidoptera) Lacewings (Neuroptera) Dragonflies & Damselflies (Odonata) Bugs (Hemiptera) Beetles (Coleoptera) Flies (Diptera) Bees, ants & wasps (Hymenoptera)
