BIOL 1407 – General Biology II Review Sheet for Exam 3 Mr. Dees (please note that this is not intended to be a totally inclusive list – just a place to start) Chapter 32 origins/evolution of animal life characteristics of kingdom animalia development of animal embryo blastula, gastrula, gastrulation, blastocoel, blastopore hox genes choanoflagellates understand the traditional systems of classification as discussed in class parazoa-eumetazoa – diploblatic - triploblastic symmetry – radial – bilateral acoelomate-pseudocoelomate-coelomate protostome –deuterostome phylogenetic tree of animal phyla Know the animal phyla, subphyla (if discussed) and classes of animal groups discussed in class Chapter 33 (remember: notes are from three lectures a, b, & c) ***for all groups of animals – you need to know the examples discussed in class and their anatomy*** invertebrates/vertebrates • Phylum porifera o know general characteristics parazoa choanocytes feeding mode amoebocytes spiclues monoecious sessile o know general anatomy of a sponge o classification of sponges – know characteristics of examples discussed in class Grantia bath and finger sponges venus looking glass • Phylum Cnidaria o know general characteristics eumetazoa –diploblastic – endo-ectoderm (epidermis/gastrodermis) radial symmetry polyp/medusae - tentacles digestive system – incomplete – only one opening – mouth cnidocytes/nematocysts motile primitive nerve net sexual and asexual (budding) mesoglea classification of cnidarians – know chrs of each example discussed in class (see table 33.1) hydroids Hydra • • Obelia – life cycle • Portuguese-man-o-war True Jellies • Sea nettles Aurelia • Cubozoid jellies • box jellies • highly toxic Anthozoans • sea anemone • corals – importance of coral reefs Phylum Platyhelminthes – flat worms o know general characteristics triploblastic – endo, ecto, mesoderm bilateral symmetry acoelomate simple nervous system protonephridia/flame cells incomplete digestive system o classification of flatworms • Dugesia –planaria o know the anatomy eye spots auricles pharynx mouth gastrovascular cavity nervous system tapeworms • parasitic • know life cycle – definitive/intermediate host • anatomy – scolex, proglottid, monoecious Taenia • flukes • parasitic Schistosoma – know life cycle • o cercaria o dioecious Phylum nematoda – roundworms o know characteristics pseudocoelomate complete digestive system bilateral symmetry cuticle body form dioecious o importance of nematodes o • • know life cycles (hosts and vectors) and general information for the following parasites Ascaris lumbricoides – human intestinal roundworm Necator americanus – hookworm Wucheria bancrofti - elephantiasis Dracunculus medinensis – Guinea worm Loa loa – eye worm Trichinella spiralis – trichina worm Enterobius vermicularis - pinworm Dirofilaria immitis – heartworm Coelomate protostomes – recall the differences of protostomes and deuterostomes Phylum mollusca – the mollusks o know characteristics o soft body/dorsal shell (in most) o dioecious o body plan – foot, mantle, visceral mass, radula o circulatory system – open (all but one group) o classification of mollusks – know chrs for each group chitons gastropods - snails, slugs – torsion bivalves - mussels, clams ,oysters - anatomy cephalopods - advanced!!!! squid, octopi, nautilus • understand the success of these inverts Phylum annelida – segmented worms o evolutionary landmark – metamerism o know characteristics discussed o classification of segmented worms Lumbricus terrestris – earthworm • know anatomy polychaetes Nereis – sandworm leeches – ectoparasites • hirudin Phylum Arthropoda – arthropods o know characteristics bilateral symmetry jointed appendages exoskeleton-chitin-ecdysis segmented body tagma – head, thorax, abdomen open circulatory system respiratory structures tracheal tubes, gills, book lung o trilobites o classification of arthropods (includes subphyla!) Chelicerates • arachnids – know examples and anatomy • merostomes - horshoe crab – Limulus Crustaceans • Know examples and anatomy of appendages Myriapods – know characteristics • millipedes • centipedes o • • • • Hexapods – insects o metamorphic life cycle Coelomate deuterostomes Phylum echinodermata o know characteristics spiny skin - endoskeleton water vascular system pentaradial symmetry/bilateral symmetry dioecious o classification of echinoderms sea stars – basic anatomy sea urchins, sand dollars, etc.. sea cucumbers • •
