  1. Four Kingdom Trip

  2. Protists WHAT?? • Eukaryotic • Heterotroph or Autotroph • Single or Multicelled (algae) • Animal Like (protozoa) • Amoeba (rhizopoda), sleeping sickness • Plant Like (algae) • Euglena, chlorophyta • Fungi Like (slime molds)

  3. Fungi - Characteristics • Eukaryotic, Heterotrophic, multi or single cell • External Digestion • Mycelium • Hyphae • Chitin • Plasmogamy/Karyogamy

  4. Fungi – Phyla • Zygomycota – bread mold • Ascomycota – yeast • Basidiomycota – shrooms, fairies • - • Lichen – ascomycota + algae • Mycorrhizae – zygomycota + plant roots • Haustoria – parasitic (into plants)

  5. Plants!!!!!!!! • Autotrophic • Multicellular • Embryophytes • Cuticle

  6. Plants – Phyla • Bryophyte  moss • Gametengia  archegonium, antheridium • No vascular tissue • Seedless vascular  Pterophyta, • Flagellated sperm, microspore, megaspore • GOOD vascular tissue • Conifer  pine, cone bearing • Gymnosperms Naked seed (no ovary) • BETTER Vascular tissue (trachieds) • Angiosperms  Flowers • Ovary, double fertilization • Embryo + endosperm • BEST vascular tissue (vessel elements)

  7. Plant (angiosperms) • Cell Types – Characteristics? • Parenchyma • Collenchyma • Sclerenchyma • Tissue Types – Functions?? • Ground Tissue • Dermal Tissue • Vascular tissue

  8. Plant (angiosperms) • Growth • Indeterminate • Primary Growth • Apical Meristem • Secondary Growth • Lateral meristems • Vascular cambium • Cork cambium

  9. Plant (angiosperms) • Reproduction • The FLOWER • Pollination • Fertilization • Germination

  10. Plant (angiosperms) • Hormones • Auxins – acid growth, apical dominance, phototrophism • Cytokinins – cell division, root, lateral growth • Gibberelins – bolting • Ethylene – ripening, leaf abscission • Abscisic Acid – stress, inhibit growth, promote dormancy • Other Responses • Gravitropism, Phytochrome, signal transduction

  11. Animal Kingdom • Classified according to; • Tissue complexity • Body symmetry • Cephalization • Gastrovascular Cavity • Coelom • Segmentation • Protostomes or Deuterostomes (us)

  12. Animal Kingdom • Phyla • Porifera – sponge • Cnidaria – jellyfish • Platyhelminthes – tapeworm (flat) • Nematoda (roundworm) • Rotifera (microscopic ) • Mollusca – snails, clams octopus • Annelida – earthworm (segments) • Arthropoda – House fly (exoskeleton) • Echinodermata – Starfish (only other deuterostome) • Chordata – us (notocord )

  13. Animal – OK, more fun • Morula • Blastula • Gastrula • Ectoderm • Mesoderm • Endoderm • Archenteron…

  14. Evolution – Natural Selection Variation (mutation) Over-reproduction Competition Varried survival success (reproductive success)

  15. Evolution - Populations Microevolution HW equilibrium If no NS, then no allele change Sample ProblemProblem: 1 in 1700 US Caucasian newborns have cystic fibrous. C for normal is dominant over c for cystic fibrous. - Calculate carrier frequency Gene Flow Bottleneck Founder Heterozygote advantage Balanced Polymorphism

  16. Evolution - Species • Definition of species • Modes of speciation • Sympatric vs. allopatric • Interspecies barriers • Prezygotic • Postzygotic • Gradualism vs. punctuated equilibrium
