  1. Diversity

  2. Three Domains of Living Things The Tree of Life The Three Domains of Life Represent the Earliest Branches in Evolutionary History

  3. Bacteria Archaea

  4. Dinoflagellates move with two whiplike flagella. Euglenoids have a single flagellum Diatoms have silica shells. Protists: Algae Photosynthetic Using Chloroplasts • Single-celled Algae

  5. Protists: Algae Photosynthetic Using Chloroplasts Multicellular Algae

  6. Water mold Slime mold Fungus-Like Protists Heterotrophic by Absorption

  7. Sarcodines movewith pseudopodia Sporozoans have nomeans of locomotion Animal-Like Protists: Protozoa • Heterotrophic by Ingestion • Distinguished by Locomotion

  8. Ciliates use ciliafor movement. Zooflagellates use flagella for movement. Animal-Like Protists: Protozoa • Heterotrophic by Ingestion • Distinguished by Locomotion

  9. Zygote Fungi • Live in soil and on decaying plant matter • Zygoporangia = reproductive structures producing spores

  10. Sac Fungi • Ascus = sac that surrounds spores

  11. Club Fungi • Basidium = club-shaped reproductive structure that produces spores

  12. Imperfect Fungi • Sexual reproduction has not been observed

  13. Bryophytes Seed Plants Tracheophytes Evolutionary Treeof Major Plant Groups Liver-worts Mosses Ferns Gymno-sperms Angio-sperms Bryophyta Pterophyta Anthophyta Conifero-phyta Flowers & Fruits appear Shows increasing adaptations for land dwelling True vascular tissue& lignin appear Seeds andpollen appear Ancestral Algae

  14. Mosses Ferns

  15. AngiospermsFlowering Plants GymnospermsSeed Plants without Flowers

  16. Categories of Angiosperms

Annelidasegmentedworms Evolutionary Sequence for Animal Groups

  31. Comparison of Protostomes to Deuterostomes Mouth forms from first opening Mouth forms from second opening cleavage = cell divisions following fertilization blastopore = first opening in embryo

  32. P. Echinidermatasea stars P. Chordata C. Mammaliawhale, mouse Fishes(5-7 classes) C. “Reptilia” lizards C. Amphibia frog C. Avesbirds Evolutionary Sequence for Animal Groups Sub P. Urochordata Sub P. Cephalochodata Sub P. Vertebrata

  33. Phylum Chordata Subphylum Urochordatatunicates, sea squirts Subphylum Cephalochordatalancelets

  34. Phylum ChordataClasses of Sub-Phylum Vertebrata5-7 classes of fish, including • Class Agnatha • jawless fishes • Class Chondrichhthyes • cartilaginous fish • Class Osteichthyes • bony fish

  35. Phylum ChordataClasses of Sub-Phylum Vertebrata • Class Amphibia • frogs, toads, salamanders • Class Aves • birds • Class Reptilia • lizards, snakes, turtles, alligators

  36. Phylum ChordataClasses of Sub-Phylum Vertebrata • Class Mammalia:monotremes, marsupials, placentals
