7. Photo: Tambako The Jaguar Did you know that nearly 99% of chimp genes are the same as human genes? They are our closest relative!

8. Plant or Animal? Photo: 3dpete Photo: ReflectedSerendipity Most animals move from place to place, whereas plants do not. Most plants have green leaves and use them to make their own food. Animals cannot do this, so they have to eat other plants or animals to get energy .

9. 1. Vertebrate or invertebrate? Vertebrates are animals with a backbone. They make up less than 3% of the world’s animals.

10. What makes an animal a mammal?

11. What makes an animal a bird?

12. What makes an animal a reptile?

13. What makes an animal an amphibian?

14. What makes an animal a fish?

15. Invertebrates There are about 30 million species of invertebrates in the world! They can be divided into many groups, each with very different characteristics.

16. Photo: Kathi Insects L argest group of invertebrates 3 parts to their bodies 2 eyes 2 antennae 6 jointed legs at some point in their lives Often have wings w asp, bee, butterfly, moth, beetle, ant, fly, dragon fly, praying mantis

17. Photo: Martin Cooper Arachnids 2 parts to their body 8 legs 2 pincers for biting or piercing prey No antennae spider, scorpion, tick, mite, daddy-long-legs (harvestman)

18. Photo: sankax Crustaceans A hard outer shell or case 10 or more legs 2 pairs of antennae woodlouse, crab, lobster, barnacle, shrimp

19. Annelids Only one major part to their bodies N o limbs Bodies divided into segments Worm, leech

20. Molluscs One main part to their body Some have a shell All have one muscly foot or tentacles to help them move around Most are slimy to help them slide along the ground Photo: bramblejungle s nail, slug, octopus, oyster, mussel, clam , squid

21. Photo: bramblejungle Myriapods The word “ myriapod ” literally means “many legs”. Do you know which is the centipede and which is the millipede ? Clue: millipedes are cylindrical (like a pencil) and have up to 200 pairs of legs, centipedes are flattened and have between 15 and 177 pairs of legs. Centipede , millipede Photo: Colin Avison

22. Photo: Selbe Lynn Live in the ocean Most have arms or spines that radiate from the centre of their body Central body contains organs and mouth for feeding Echinoderms s tar fish, sea urchin, sea cucumber

23. Cnidarians Photo: Wally Gobetz Water animals that have a simple (usually symmetrical) body with a mouth opening Stinging cells on tentacles around the mouth catch prey j ellyfish, coral, sea anemone

24. 2. Warm-blooded or cold-blooded? Photo: David Stanley Warm-blooded animals, like these penguins, can stay active whatever the temperature of their surroundings. As the outside temperature rises, this chameleon will become more active. As the outside temperature drops, the chameleon slows down. Photo: Tambako The Jaguar

25. Photo: Michael Pennay Are bats birds or mammals?

26. Flowering plants Make up over 80% of all plants on Earth Around 352,000 different species (estimate by scientists from Kew Gardens 2008) Photo: solarisgirl

27. Photo: James Petts Conifers e.g. pine trees use cones to house their seeds Some non-flowering plants use seeds to reproduce

28. Some non-flowering plants do not produce seeds and use spores to reproduce Photo: Kristine Paulus Ferns produce spore casings on the underside of their leaves. When the casings dry out, the spores are released into the air.
