1. ANIMALS WHAT IS AN ANIMAL? ANIMALS ARE MANY CELLED ORGANISMS THAT MUST OBTAIN THEIR FOOD BY EATING OTHER ORGANISMS. NEED WATER, FOOD, AND OXYGEN TO SURVIVE HETEROTROPHS REPRODUCE SEXUALLY CAN BE CARNIVORES (MEAT EATING), HERBIVORES (PLANT EATING) OR OMNIVORES (BOTH PLANTS AND ANIMALS)

2. SYMMETRY WHAT IS SYMMETRY? RADIAL SYMMETRY- THE QUALITY OF HAVING MANY LINES OF SYMMETRY THAT ALL PASS THROUGH A CENTRAL POINT. EXAMPLE - BICYCLE WHEEL BILATERAL SYMMETRY- line symmetry, the quality of being divisible into two halves that are mirror images.

3. SYMMETRY

4. SPONGES CHARACTERISTICS stay in one place/ do not move no symmetry/ irregular shapes lack tissue and organs HOW IS A SPONGE DIFFERENT FROM A PLANT? ANSWER: IT HAS TO TAKE FOOD INTO ITS BODY HOW DOES A SPONGE GET ITS FOOD AND OXYGEN? MOVING CURRENTS BRING IN FOOD (BACTERIA AND PROTISTS) AS WELL AS OXYGEN (DIFFUSION)

5. SPONGES

6. CNIDARIANS CHARACTERISTICS STINGING CELLS TAKE FOOD INTO A HOLLOW CENTRAL CAVITY CARNIVORES SPECIALIZED TISSUE (MUSCLE/NERVE SYSTEM) RADIAL SYMMETRY 2 BODY SHAPES - POLYP AND MEDUSA EXAMPLES - JELLYFISH, SEA ANEMONES, AND CORALS

8. LIFE ON A CORAL REEF

10. WORMS CHARACTERISTICS INVERTEBRATES LONG NARROW BODIES WITHOUT LEGS HAVE TISSUES ORGANS AND ORGAN SYSTEMS BILATERAL SYMMETRY (HEAD AND TAIL ENDS) THREE GROUPS - FLAT, ROUND, SEGMENTED SIMPLEST ORGANISMS WITH A BRAIN CAN EXHIBIT REGENERATION (ABILITY TO REGROW A BODY PART).

11. WORMS FLATWORMS - FLAT, PARASITES THAT OBTAIN THEIR HOSTS. EXAMPLES: PLANARIANS, FLUKES, AND TAPEWORMS ROUNDWORMS - ROUND BODIES THAT HAVE A DIGESTIVE SYSTEM THAT IS LIKE A TUBE, OPEN AT BOTH ENDS. FOOD ENTERS THROUGH THE MOUTH AND EXITS AT AN ANUS SEGMENTED WORMS - RINGS SEPERATED BY GROOVES/LINKED SECTIONS EX.EARTHWORMS, LEECHES

12. WORMS

14. MOLLUSKS CHARACTERISTICS INVERTEBRATES SOFT BODIES PROTECTED WITH A HARD SHELL MANTLE - TISSUE WHICH COVERS THE INTERNAL ORGANS AND PRODUCES THE SHELL HAVE A “FOOT” USED FOR DIGGING, MOVING, OR CATCHING PREY BILATERAL SYMMETRY KIDNEY,GILLS, AND REDULA (FLEXIBLE RIBBON OF TEETH (WORKS LIKE SAND PAPER) EXAMPLES - CLAMS, OYSTERS, SCALLOPS, SNAILS, OCTOPUSES.

16. ARTHROPODS CHARACTERISTICS INVERTEBRATE EXTERNAL SKELETON / EXOSKELETON SEGMENTED BODY JOINTED ATTACHMENTS CALLED APPENDAGES EX. WINGS, MOUTH PARTS, LEGS, ARTHRO - JOINTPOD-FOOT OR LEG MOLTING - PROCESS OF SHEDDING AN EXOSKELETON WHY WOULD ARTHROPODS UNDERGO MOLTING?

17. TYPES OF ARTHROPODS CRUSTACEANS - TWO OR THREE BODY SECTIONS AND THREE PAIRS OF APPENDAGES FOR CHEWING, 5 OR MORE PAIRS OF LEGS, TWO PAIRS OF ANTENNA (SENSE ORGANS) EXAMPLES : SHRIMP, LOBSTER ARACHNIDS - ONLY HAVE TWO BODY SECTIONS, 8 LEGS, NO ANTENNAE EXAMPLES : SPIDERS, TICKS, MITES, SCORPIONS INSECTS - 3 BODY SECTIONS, SIX LEGS, ONE PAIR OF ANTENNAE, ONE - TWO PAIRS OF WINGS EXAMPLES : BUTTERFLIES, BEES, BEETLES, FLIES,

21. ECHINODERMS CHARACTERISTICS RADIAL SYMMETRY INVERTEBRATE LIVES ON OCEAN FLOOR “SPINY SKIN” ENDOSKELETON (INTERNAL SKELETON) EXAMPLES: SEA STARS, SEA URCHINS, SAND DOLLARS, SEA CUCUMBERS
