  1. CLASSIFYING ORGANISMS LS CH 7 SEC 4

  2. GOAL/PURPOSE • STUDENTS WILL BE ABLE TO EXPLAIN WHY BIOLOGISTS CLASSIFY ANIMALS. • RELATE THE LEVELS OF CLASSIFICATION BETWEEN ORGANISMS • LIST CHARACTERISTICS USED TO CLASSIFY ORGANISMS INTO GROUPS.

  3. CHOOSE 5 WORDS A DEFINE

  4. ANIMAL KINGDOM- WHAT IS YOUR FAVORITE ANIMAL?

  5. LIST 5 FACTS ABOUT YOUR FAVORITE ANIMAL

  6. WHY CLASSIFY? • KEY- SCIENTIST HAVE IDENTIFIED MORE THAN 1.5 MILLION SPECIES • KEY- SCIENTIST GROUP ORGANISMS BASED ON SIMILARITIES IN THEIR FEATURES, BEHAVIOR, AND DNA. • CLASSIFICATION- IS THE PROCESS OF GROUPING THINGS BASED ON THEIR SIMILARITIES

  7. KEY-Q? THE WAY SCIENTIST ORGANIZE ALL LIVING THINGS IS CALLED THE?

  8. CONT’D • KEY- BIOLOGIST USE CLASSIFICATION TO ORGANIZE LIVING THINGS INTO GROUPS SO THAT THE ORGANISMS ARE EASIER TO STUDY. • TAXONOMY- IS THE SCIENTIFIC STUDY OF HOW LIVING THINGS ARE CLASSIFIED

  9. KEY- COPY THE LEVELS BIGGEST TO SMALLEST

  10. OCEAN LIFE IS JUST AS AMAZING CAN YOU SEE THE SHARK?

  11. NAMING SYSTEM • KEY- TAXONOMY INVOLVES NAMING OF THE ORGANISM. • BINOMIAL NOMENCLATURE- THE NAMING SYSTEM USED THAT GIVES EACH ORGANISM A 2-PART NAME. • EX- FELIS CONCOLOR- MOUNTAIN LION OR FELIS DOMESTICUS- HOUSE CAT

  12. COPY CLASSIFICATION OF A ORCA LOOK UP TH 2 PART NAME FOR ORCA

  13. CHOOSE 3 DIFFERENT ANIMALS AND LIST THEIR REGULAR NAMES AND LOOK UP THEIR 2 PART SCIENTIFIC NAMES

  14. CONT,D • KEY -THE FIRST WORD IN THE SYSTEM IS CALLED THE GENUS. • GENUS- IS A CLASSIFICATION GROUPING THAT CONTAINS SIMILAR, CLOSELY RELATED ORGANISMS. • EX- ALL CATS BEGIN WITH ‘FELIS’ ‘felidae’plural • KEY- THE SECOND WORD IN THE NAME OFTEN DESCRIBES A DISTINCTIVE FEATURE OF AN ORGANISM, SUCH AS WHERE IT LIVES OR ITS APPEARANCE.

  15. COPY

  17. LEVELS OF CLASSIFICATION • KEY- MOST BIOLOGISTS TODAY CLASSIFY ORGANISMS INTO EIGHT LEVELS • KEY- THE MORE LEVELS THAT 2 ORGANISMS SHARE, THE MORE CHARACTERISTICS THEY HAVE IN COMMON.

  18. COPY NAMES ONLY

  19. KEY- THE THREE DOMAINS (BIG CATEGORIES) • 1. BACTERIA- • 2. ARCHEA- • 3. EUKAYRA- INCLUDES THE PROTIST, FUNGI, PLANTS AND ANIMALS KINGDOMS • KEY- ORGANISMS ARE PLACED INTO DOMAINS AND KINGDOMS BASED ON THEIR CELL TYPE, THEIR ABILITY TO MAKE FOOD, AND THE NUMBER OF CELLS IN THEIR BODIES

  20. DOMAIN- BACTERIA • PROKARYOTES- WHOSE CELLS LACK A NUCLEUS • KEY- FOUND EVERYWHERE IN YOUR FOOD, ON YOUR DESK, IN YOUR BODY • KEY- SOME ARE AUTOTROPHS (MAKE THEIR OWN FOOD) AND SOME ARE HETEROTROPHS (DON’T MAKE OWN FOOD)

  21. DOMAIN- ARCHEA • KEY – NAME MEANS “ANCIENT” • FOUND IN DEEP OCEAN VENTS AND OTHER EXTREME ENVIRONMENTS • HOT SPRINGS, SWAMPS, INTESTINES OF COWS • UNICELLULAR PROKARYOTES, • AUTO AND HETEROTROPHS

  22. DOMAIN - EUKARYA • KEY- SCIENTIST CLASSIFY PROTIST, FUNGI, PLANTS, AND ANIMALS • EUKARYOTES- ORGANISMS WITH CELLS THAT CONTAIN NUCLEI • FROM SEAWEEDS, TO MUSHROOMS, TO TOMATOES TO DOGS ALL FALL INTO DOMAIN EUKARYA

  23. BRAINPOP • http://www.brainpop.com/science/diversityoflife/sixkingdoms/

  24. WRITE THE QUESTIONS AND ANSWERS • 1- WHY DO BIOLOGIST CLASSIFY? • 2- LIST THE LEVELS OF CLASSIFICATION BEGINNING WITH DOMAIN • 3- SEARCH THE CLASSIFICATION OF HUMANS. NAME THE EIGHT LEVELS.
