Exam I Review BIOL 1104 Labs I-V Lab I: Ecology Concepts • Ecological Pyramid – Draw and label using appropriate terminology – Give examples at each trophic level – Explain the shape • Rule of Ten – Only 10% of the total available energy is transferred from one trophic level to the next. Energy Pyramid and the “Rule of Ten” The Story of The Otter, The Sea Urchin, The Kelp Field & The Killer Whale Specimens • Identify the organism • Autotroph or Heterotroph? • What trophic level does it represent? Labs II & III: Plant Diversity Plant Classification • Bryophytes (moss) • Tracheophytes – Seedless tracheophytes (fern) – Seed tracheophytes • Gymnosperms (conifers) • Angiosperms (flowering plants) – Monocots (corn) – Dicots (bean) Concepts (1) • Requirements for Terrestrial Life – Cuticle – Increased rigidity – Vascular tissue – Decreased reliance on water for reproduction (seed) • Alternation of Generations – The alternation of a plant’s life cycle between its gametophyte and the sporophyte generations Concepts (2) • Gametophyte Generation – Genetic content = N – Gametophytes produces gametes via mitosis – Gametophyte structures: spores, gametophyte plant, antheridia/archegonia, sperm/egg • Sporophyte Generation – Genetic content = 2N – Sporophytes produce spores via meiosis – Sporophyte structures: zygote/embryo, sporophyte plant, sporangia, spore mother cell Concepts (3) • Homosporous Life Cycle – Produces only one type of spore – Bryophytes and Seedless Tracheophytes • Heterosporous Life Cycle – Produces two different types of spores • Megaspores (female) • Microspores (male) – Seed Tracheophytes Bryophytes • Requirements for terrestrial life? • Dominant generation? • What generation is pictured in B? What is its genetic content? A B What organism? What generation? Identify reproductive structures. What do they produce? By what process? Seedless Tracheophytes • Requirements for terrestrial life? • Dominant generation? What organism? What generation? Identify the structures pictured here. What is their genetic content? What do they produce? By what process? What organism? What generation? Identify reproductive structures. What do they produce? By what process? Seed Tracheophytes • Requirements for terrestrial life? • Dominant generation? • Two major divisions? • Reproductive strategy? Seed Tracheophytes • Heterosporous Life Cycle – Female: megasporangia (2N) → megaspores (N) → megagametophyte (N) MiMature pollene = grains – Male: microsporangia (2N) → microspores (N) → microgametophyte (N) Seed Tracheophytes • Gymnosperms • Angiosperms – Non-flowering – Flowering – Evergreen – Monocots and Dicots – Sporangia found in – Sporangia found in cones: flower parts: • Ovulate cone • Pistil (female) (female) – Stigma • Staminate cone – Style (male) – Ovary • Stamen – Anther – Filament Identify the reproductive structures at A and B. Which is male? Which is female? To which generation do they belong? What parts are included in each structure (C-G)? A B B A E C C F D G Monocot vs. Dicot Monocot (corn) Dicot (bean) -- roots -- cotyledon -- vascular bundles -- venation -- flower petals Angiosperms • Monocots (corn) • Dicots (bean) – One cotyledon – Two cotyledons – Fibrous roots – Tap root – Vascular bundles – Vascular bundles throughout stem arranged in ring in stem – Parallel veins in leaves – Netlike veins in leaves – Flower petals in groups – Flower petals in groups of 3’s of 4’s or 5’s Identify: 1) Dominant Generation 2) Reproductive Structures 3) Division/Phylum 1 Sporophyte 1 Sporophyte 2 Carpel 1 Sporophyte 2 Ovulate Cone Stamen 1 Gametophyte 2 Archegonia Staminate Cone Prothallus 3 Anthophyta 2 Archegonia Antheridia 3 Coniferophyta Antheridia 3 Pterophyta Angiosperms C 3 Bryophyta Gymnosperms Show: Ferns B A) Development of vascular tissue Mosses B) Development of seed- A encased zygote C) Development of flowers and fruits Labs IV & V: Animal Diversity Organization Symmetry Cellular Asymmetrical Tissue Radial Organ Bilateral Digestive System Diploblastic: Endo + Ecto Triploblastic: All 3 Cellular: No Germ Layers No Symmetry Tissue: 2 Germ Layers Symmetry (Radial) Organ: 3 Germ Layers (has to have!) Symmetry (Bilateral) Coelom Development (has a mesoderm!) Now lets talk about the Coelom!! Flatworms  Roundworms  What is a Coelum? A fluid-filled cavity lined with epithelium, derived from the mesoderm, that houses organs. Fluid allows: ability of organs to move and grow a cushioning for the organs Acoelomate Pseudocoelomate Eucoelomate Identify based on: Vertebrates 1) Level of Organization Star fish 2) Body Cavity 3) Germ Layers - [Diploblastic or Triplobastic] Mollusc Seg. Worm Arthopod 4) Symmetry 5) Digestive System Additional: Special Characteristic Rotifer Roundworm Organ Flatworm Organ Eucoelomate Jellyfish Comb Jelly Eucoelomate Triploblastic Organ Organ Triploblastic Bilateral sponge Pseudocoelomate Acoelomate Bi-lateral Complete Tissue Tribloplastic Triploblastic Acoelomate Complete Notochord Cellular Bi-lateral B-ILATERAL** N/A Diploblastic Complete Jointed Appendages Cavity Echniodermata / Chordata N/A Radial Muscle Movement Cavity **Cephalization Asymmetrical Mollusca / Annelida / Arthodopa Sp. Cells Nematocysts Rotifera / Nematoda Spicules Platyhelminthes Cnidaria Porifera Phylum Porifera • Cellular level of organization • No germ layers • Spicules for support • Colar cell Phylum Cnideria • Tissue level of organization • Diploblastic • Radial symmetry • Cnidoblasts with nematocysts • polymorphic Phylum Platyhelminthes • Organ level of organization • Triploblastic • Acoelomate • Bilateral symmetry • Cephalization • Blind sac Phylum Nematoda • Pseudocoelom • Tube within a tube body plan Phylum Rotifera • Psuedocoelom • Heterotroph • Primary consumer Phylum Mollusca • Eucoelomate protostome • Open circulatory system with hemocyanin • Mantle • Muscular foot Phylum Annelida • Closed circulatory system with hemoglobin • Longitudinal and circular smooth muscle Phylum Arthropoda • Exoskeleton with jointed appendages • Subphylum Chelicerata • Striated muscle – Class Merostomata • Well developed – Class Arachnida nervous system • Subphylum Crustacea • Subphylum Uniramia – Class Insecta – Class Chilopoda – Class Diplopoda Phylum Echinodermata • Eucoelomate deuterostomes • Dermal endoskeleton • Bilateral symmetry as larvae; bilateral and pentaradial symmetry as adults • Water vascular system with tube feet Phylum Chordata (1) • Notochord • Pharyngeal gill slits • Postanal tail • Dorsal hollow nerve cord Phylum Chordata Sub-Phylums Urochordata Vertebrata Cephalochordata Super Classes Agnatha Gnathostomata Classes Chondrichthyes Osteichthyes Amphibia Reptilia/Aves Mammalia Class Chondrichthyes • Cartilaginous fishes • No swim bladder • Respiration: Gills Class Osteichthyes • Bony fishes • Swim bladder for buoyancy • Respiration: Gills Class Amphibia • 1 land vertebrates • Ectothermic, aka “cold-blooded” • Dual life • Respiration: Lungs 50% Skin 50% Class Reptilia • Complete terrestrial life • Ectotherms • Respiration: Lungs • Lay amniotic eggs lizards Class Aves (Really Reptilia) • Feathers • Endothermic, aka warm blooded • Lay amniotic eggs Subphylum Vertebrata Superclass Gnathostomata Class Mammalia • Mammary glands • Hair • Two sets of teeth • Endothermic
