Bio 156 Lab 5 Porifera, Cnidaria, Ctenophora, Platyhelminthes, Annelida, Mollusca

5 ways to classify animals

Symetry, number of germ layers, type of coelom, body plan, presence or absence segmentation

Phylum porifera eukaryotic or prokaryotic, multi or single celled, what kind of feeders are they? Level or organization to body complexity? Symetry?

Eularyotic, multicellular, ingestive hererotrophs, cellular level, asymetrical

3 body types sponges from least to most complex

Asconoid, syconoid, leuconoid

Phylum cnidaria body symetry, level or body organization, type of germ layering, name of stinging cells

Radial, tissue level, diploblastic, nematocysts

Diploblastic vs triploblastic

Having two germ layers ectoderm and endoderm vs having three, ectoderm, mesoderm, and endoderm

Phylum ctenophora type of symetry, level of body org, type of stinging cells, swim using, type of digestive tract

Biradial symetry, tissue level, colloblasts, rows of ctenes, complete

Protostome lineage divided into what two groups? What does each group contain

Lophotrochozoans which have a locophore larvae and include platyhelminthes, rotifera, annelida, and mollusca

Ecdyzoans which are molting animals and include Nematoda, Onychophora, and Arthropoda

1 ex of acelomate and pseydocoelomate; 5 coelomate phylums

Flatworms are acelomate, roundworms are pseudocoelomates, coelomates include mollusks, annelids, arthopods, echinoderms, and chordates

Phylum platyhelminthes symetry type, germ layer type, coelom type, body level of organization, type of digestive track

Bilateral, triploblastic, acoelomate, organ system level, incomplete digestive tract

Phylum annelida type of coelom, type of germ layering, type of digestive system, types of muscles

Coelomates, triploblastic, complete, circular and longitudinal

Phylum mollusca protostome or deuterostome, tybe od body cavity, epidermal tissue that secretes shell name, type of circulatory system

Protostomes, coelomates, mantle, open

Spicules vs spongin in porifera

Crystalline internal structures vs proteinaceous fibers

Hydra gametes produced vs polyps and medusa produced…

Sexually vs asexually

Fasciola spp what is

Parasitic fluke that have snails as intermediate hosts and cattle as definitive hosts, can pass to humans

Clonorchis sinensis

Parasitic fluke snails as int host, fish as definitive host, cayse of liver disease in pple

Taenia saginata and T solium

Tapeworm from undercooked pork and cattle

Diplydium caninum

Dog and cat tapeworm, can also fet in pple

Phylum rotifera protostome or deuterostome, multi or single celled, circukatory sustem?

Protostome, multicellular, no circulatory system
