Bio211 10/1/13Kingdom AnimaliaWhat phylum do sponges belong to? What are the characteristics of this phylum?(Characteristics: symmetry, organization of tissues, type of body cavity (coelom), pattern of development (-stome))How do sponges create a water current for feeding? What is special about these cells, and what protists are they possible descendants of? Try drawing a picture of this cell/the ancestral protist.How do sponges reproduce?Cnidarians (Jellyfish, anemones, coral, hydrozoans)True or False: (If False, why?)Cnidarians have true tissues (muscles, nerves) Cnidarians have three body formsCnidarians are bilaterally symmetricalCnidarians develop from 2 germ layers (diploblastic)Cnidarians are predatorsWhat is the name of the specialized cell type that only Cnidarians have? ______________What is a nematocyst?Draw a medusa and a polyp.Lophotrochozoans (Flatworms, Segmented Worms, and Mollusks)Which lophotrochozoans are acoelomate? Pseudocoelomate?1Bio211 10/1/13What are the two ciliated feeding structures that lophotrochozoans are known to have? Label which is for the adult stage and which is for the larval stage.Are lophotrochozoans protostomes or deuterostomes? Diploblastic or triploblastic?PlaythelminthesWhich class of flatworm is NOT parasitic? (Circle)Monogenea(monogeneans) Cestoda(tapeworms)Turbellaria(planarians) Trematoda (flukes)What is reproductive effort and how does it differ between free-living and parasitic flatworms?Circle the parasitic characteristicsLow reproductive rate High reproductive rateAttachment organs No organsMobile larval stages Stationary larval stagesLack of external covering Tough/camouflaged external coveringComplete set of organs Reduction of organs/organ systemsCan change host behavior Can’t affect host without being discoveredDraw out a (simple) parasitic life cylePhylum Annelida (earthworms, marine worms, leeches)As far as circulatory systems, coeloms, digestive systems, and body segments go, what do all annelids have in common?What are Annelida’s two well-developed adaptations?2Bio211 10/1/13How do earthworms reproduce? (Draw a picture if it helps)Phylum Mollusca (Mollusks)What 5 parts do “all” mollusks have? (We will be drawing a rough diagram for each class)1. 2. 3. 4. 5. Class Gastropoda (snails, slugs, sea slugs), Class Bivaliva (clams, mussels, oysters, cockels, scallops), Class Cephalopoda (octopi, squids, cuttlefish, nautilus)- Which class(es)… o Is the most diverse? (about 40,000 named species)o Feed using a radula?o Has an open circulatory system?o Is mostly comprised of herbivores (but have some predatory species)?o Is predatory?o Is mostly comprised of filter feeders?o Has no terrestrial species?o Are ONLY in marine habitats (no freshwater)?o Means “two shells”?o Include primarily hermaphrodites?o Use lures to attract fish?o Is very mobile?o Uses camoflauge to hunt?3Bio211 10/1/13USE THIS SPACE TO DIAGRAM THE 5 COMMON PARTS OF MOLLUSKS
