3. Slide 3 of 28 Copyright Pearson Prentice Hall The Tree of Life Evolves What are the six kingdoms of life as they are now identified?

4. 18-3 Kingdoms and Domains Slide 4 of 28 Copyright Pearson Prentice Hall The Tree of Life Evolves The six-kingdom system of classification includes: Eubacteria Archaebacteria Protista Fungi Plantae Animalia

5. 18-3 Kingdoms and Domains Slide 5 of 28 Copyright Pearson Prentice Hall The Three-Domain System Molecular analyses have given rise to a new taxonomic category that is now recognized by many scientists. The domain is a more inclusive category than any other—larger than a kingdom.

6. 18-3 Kingdoms and Domains Slide 6 of 28 Copyright Pearson Prentice Hall The Three-Domain System The three domains are: Eukarya, which is composed of protists, fungi, plants, and animals. Bacteria, which corresponds to the kingdom Eubacteria. Archaea, which corresponds to the kingdom Archaebacteria.

7. 18-3 Kingdoms and Domains Slide 7 of 28 Copyright Pearson Prentice Hall Domain Bacteria a. unicellular prokaryotes. b. thick, rigid cell walls that surround a cell membrane. c. Their cell walls contain peptidoglycan.

8. 18-3 Kingdoms and Domains Slide 8 of 28 Copyright Pearson Prentice Hall Domain Bacteria The domain Bacteria corresponds to the kingdom Eubacteria.

9. 18-3 Kingdoms and Domains Slide 9 of 28 Copyright Pearson Prentice Hall Domain Archaea a. unicellular prokaryotes. b. live in extreme environments. c. cell walls lack peptidoglycan d. cell membranes contain unusual lipids not found in any other organism.

10. 18-3 Kingdoms and Domains Slide 10 of 28 Copyright Pearson Prentice Hall Domain Archaea The domain Archaea corresponds to the kingdom Archaebacteria.

11. 18-3 Kingdoms and Domains Slide 11 of 28 Copyright Pearson Prentice Hall Domain Eukarya The domain Eukarya consists of organisms that have a nucleus. This domain is organized into four kingdoms: Protista Fungi Plantae Animalia

12. 18-3 Kingdoms and Domains Slide 12 of 28 Copyright Pearson Prentice Hall Domain Eukarya Protista a. eukaryotic b. Uni or multicellular c. Heterotrophs or autotrophs.

13. 18-3 Kingdoms and Domains Slide 13 of 28 Copyright Pearson Prentice Hall Domain Eukarya Fungi a.heterotrophs. b.feed on dead or decaying organic matter by secreting digestive enzymes into it and absorbing small food molecules into their bodies. c. multicellular (mushrooms) or unicellular (yeasts). d. Cell walls of chitin e. Made up of thin filaments of hyphae into a mass called mycelium.

14. 18-3 Kingdoms and Domains Slide 14 of 28 Copyright Pearson Prentice Hall Domain Eukarya Plantae a.Multicellular b. autotrophic and photosynthetic c. cell walls of cellulose d. moss, fern, cone and flowering plants e. chloroplast (defining organelle)

15. 18-3 Kingdoms and Domains Slide 15 of 28 Copyright Pearson Prentice Hall Domain Eukarya Animalia a. Multicellular b. heterotrophic. c. No cell walls d. Essential functions: feeding, respiration, circulation, excretion, response, movement, reproduction

17. Slide 17 of 28 Copyright Pearson Prentice Hall 18-3 Organisms whose cell walls contain peptidoglycan belong in the kingdom a.Fungi. b.Eubacteria. c.Plantae. d.Archaebacteria.

18. Slide 18 of 28 Copyright Pearson Prentice Hall 18-3 Multicellular organisms with no cell walls or chloroplasts are members of the kingdom a.Animalia. b.Protista. c.Plantae. d.Fungi.

19. Slide 19 of 28 Copyright Pearson Prentice Hall 18-3 Organisms that have cell walls containing cellulose are found in a.Eubacteria and Plantae. b.Fungi and Plantae. c.Plantae and Protista. d.Plantae only.

20. Slide 20 of 28 Copyright Pearson Prentice Hall 18-3 Molecular analyses have given rise to a new taxonomic classification that includes a.three domains. b.seven kingdoms. c.two domains. d.five kingdoms.

21. Slide 21 of 28 Copyright Pearson Prentice Hall 18-3 Which of the following contain more than one kingdom? a.only Archaea b.only Bacteria c.only Eukarya d.both Eukarya and Archaea
