1 Classification- Organisms grouped by shared characteristics and relationships

2 Levels of Classification
Domain Kingdom Phylum Class Order Family Genus Species

3 Mnemonic: Does King Philip’s Chef Only Fix Green Salads?

4 Mnemonic: Don’t Knock People Clean Out For Getting Smart

5 Taxonomy Science of identifying, naming, and classifying organisms
Carolus Linnaeus- classified by shared traits

6 Modern Classification
Presumed evolutionary relationships Common ancient ancestors (See p. 86) Branching Diagrams to illustrate

7

8 CLADOGRAM ACTIVITY

9 Scientific Names Latin/Greek Two words: Genus and species
Genus Capitalized, species not

10 Scientific Names Cont’d
Must be underlined or italicized Genus name can be given as just a Letter Ex: Tyrannosaurus rex = T.rex PRACTICE QUIZ!

11 Bellwork A SCIENTIFIC NAME IS LIKE MY NAME BECAUSE_____________
A SCIENTIFIC NAME IS DIFFERENT FROM MY NAME BECAUSE_______________________

12 Dichotomous Key Helps identify organisms Pairs of descriptions with two alternating responses (p.89) Dichotomous Key Activity

13

14 HOW IS A DICHOTOMOUS KEY LIKE A HOUSE KEY?

15

16 Kingdoms and Domains Plant or Animal? Only 2 kingdoms for long time WHY have more kingdoms been added?

17 Domains 1. Archae- single celled, can live in extreme or moderate environments 2. Bacteria – (Prokaryotic – no nucleus) Found anywhere! Can be good or bad. 3. Eukarya– (Have Nucleus) All the Kingdoms fit in this Domain!

18 Domain: Bacteria

19 Eureka! Euglena? Green, photosynthesis - plant?
But, moves with flagella & can eat when chloroplasts don’t get sun- animal?

20 New Kingdom Protista

21 Protista

22 Kingdoms in Eukarya Protista- Protozoans: animal like, or algae: plant like. Also includes slime molds and euglenoids. Fungi- Do not eat food, do not perform photosynthesis. Absorb nutrients from surroundings.

23 Kindgoms in Eukarya Plantae- eukaryotic, cell walls, perform photosynthesis to obtain energy. Animalia- complex, multi cellular, can find and eat their own food, often rely on other kingdoms such as plants.

24 Fungus

25 Plantae

26 Animalia

27 Plant and Animal Cells

28 Domain/Kingdom Foldable
1. Domain Eukarya/Kingdoms 2. How it gets energy 3. Any subgroups (ex: Protista has protozoa, plant-like, and fungus-like 4. 3 characteristics examples Section 2 – Ch. 2
