Interpret Tables Which domains have unbranched lipids in their cell membranes Interpret Tables Which domain has just one type of RNA polymerase Analyze Data On the basis of this table, how are archaea different from bacteria
18.3 Building the Tree of Life Ch 18 Classification 18.3 Building the Tree of Life
Six-Kingdom System of Classification Eubacteria Archaebacteria Protista Fungi Plantae Animalia.
Number of kingdoms has changed and varies depending on source Started off as plant or animal.
Five kingdoms was very common Broke bacteria up into two kingdoms.
Domain Larger, more inclusive category than a kingdom Three Domains Bacteria (Eubacteria) Archaea (Archaebacteria) Eukarya (all eukaryotes.
The Tree of All Life Shows current hypotheses regarding evolutionary relationships among the taxa.
Domain Bacteria Eubacteria Thick, rigid walls containing peptidogylcan Very, very diverse.
Domain Archaea Archaebacteria Live in some extreme environments Lack peptidoglycan Cell membranes contain unusual lipids that are not found in any other organism.
Domain Eukarya Have nucleus Protista, Fungi, Plantae, and Animalia.
Protista The remaining eukaryotes Unicellular or multicellular Microscopic or much larger (10 m) Producer, consumer, or decomposer Algae, protozoa, slime molds.
Fungi Develop directly from spores Many are decomposers Multicellular with chitin cell wall (except yeast) Either sexual or asexual reproduction Mainly haploid.
Plantae Develop from embryo that lacks blastula Cell wall of cellulose Chloroplast Stores starch Mostly sexual reproduction.
Animalia Develop from embryo WITH blastula stage Heterotrophic Multicellular Microscopic to huge Many have nervous system Mostly sexual reproduction.
