Diversity of Life

Diversity of Modern Life Kingdom Monera (“Monerans”) • Smallest and simplest lifeforms • Unicellular (one-celled) • no nucleus • Bacteria and cyanobacteria Bacteria • Three basic shapes: • round (cocci) • rod (bacilli) • spiral (spirilli) Questions • What are two characteristics of the organisms in Kingdom Monera? • What is meant by unicellular? • What are the three shapes of bacteria? Kingdom Protista(“Protists”) • Single-celled or multicellular • more complex than organisms in Kingdom Monera • nucleus • protozoans (animal-like) • algae (plant-like) Protozoans • Kingdom Protista • no cell wall or chlorophyll • internal digestion • no locomotion (some) Algae • Cell walls • Chlorophyll • Photosynthetic • Placed in groups according to color and structure Questions • What are some characteristics of Protists? • What are the two types of Protists? • How are the two types of Protists different? Kingdom Fungi • Multicellular; complex • cell walls, no chlorophyll • Threadlike fungi (bread mold) • club fungi (mushrooms) • sac fungi (yeast and mildew) Questions • What are some characteristics of Fungi? • What are the three groups of fungi? [...]... fluids; no appendages (fins) • flexible skeleton made of cartilage • ectotherms Cartilaginous Fishes • Two pairs of fins; gills • ectotherms • strong teeth (sharks) • SKELETON MADE OF CARTILAGE • stingrays, skates, sharks Bony fishes • Flounder, eels, trout, and others • SKELETON MADE OF BONE • gills • streamlined bodies (narrow shape) • most numerous group of fish ... parts) Questions • What is the major similarity between mollusks, echinoderms, and arthropods? • Which group of organisms are known for regeneration? • What is regeneration? Questions • What is the largest group of animals? • Describe an invertebrate • An octopus and a clam belong to what group of invertebrates? • How is an endoskelton different from an exoskeleton? Vertebrates • Have backbones • body... leeches and marine tube worms Questions • In what major way are the three types of worms different? • How are the segmented worms MOST similar to the roundworms? Mollusks (invertebrate) • Soft-bodies, no shell: (octopus/squid) • well-developed organs • some with shells: (clams/oysters) Arthropods (invertebrate) • Largest group of animals • multiple body segments • jointed appendages (legs/arms) • exoskeleton... gymnosperm and an angiosperm? • What are three plant characteristics? • How are vascular and non vascular plants different? Sponges (invertebrate) • Simplest of the animal groups • lives in salt water attached to the bottom • Hollow central cavity • Two layers of body cells with tiny pores Coelenterates (invertebrate) • Jellyfish, hydras, and corals • two cell layers • Live in water • hollow body with a single... chlorophyll • Largest and longest-living things on Earth • Vascular or Nonvascular Nonvascular Plants • CANNOT conduct water • Example: Moss • Moist environment Vascular Plants • CAN conduct water • Capable of living in drier areas • Club mosses, Ferns, Horsetails, Gymnosperms, and Angiosperms Gymnosperms • Seed plant • name means “naked seed” • Most are conifers Angiosperms -Flowering Plants • Seed plant .
