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
CONTD

• 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 felidaeplural
• KEY- THE SECOND WORD IN THE NAME OFTEN DESCRIBES
  A DISTINCTIVE FEATURE OF AN ORGANISM, SUCH AS
  WHERE IT LIVES OR ITS APPEARANCE.

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 (DONT 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

  EIGHT LEVELS.
