18.3 Building the Tree of Life

3. Six-Kingdom System of Classification
Eubacteria
Archaebacteria
Protista
Fungi
Plantae
Animalia.

4. Number of kingdoms has changed and varies depending on source
Started off as plant or animal.

5. Five kingdoms was very common
Broke bacteria up into two kingdoms.

6. Domain Larger, more inclusive category than a kingdom Three Domains
Bacteria (Eubacteria)
Archaea (Archaebacteria)
Eukarya (all eukaryotes.

8. The Tree of All Life
Shows current hypotheses regarding evolutionary relationships among the taxa.

9. Domain Bacteria Eubacteria Thick, rigid walls containing peptidogylcan
Very, very diverse.

10. Domain Archaea Archaebacteria Live in some extreme environments
Lack peptidoglycan
Cell membranes contain unusual lipids that are not found in any other organism.

11. Domain Eukarya
Have nucleus
Protista, Fungi, Plantae, and Animalia.

12. Protista The remaining eukaryotes Unicellular or multicellular
Microscopic or much larger (10 m)
Producer, consumer, or decomposer
Algae, protozoa, slime molds.

13. Fungi Develop directly from spores Many are decomposers
Multicellular with chitin cell wall (except yeast)
Either sexual or asexual reproduction
Mainly haploid.

14. Plantae Develop from embryo that lacks blastula Cell wall of cellulose
Chloroplast
Stores starch
Mostly sexual reproduction.

15. Animalia Develop from embryo WITH blastula stage Heterotrophic
Multicellular
Microscopic to huge
Many have nervous system
Mostly sexual reproduction.
