Using the examples from the animals you have studied in this lab, give the differences between the following phyla:   Echinodermata and planaria Cnidaria and Porifera Annelida and Nematoda

Create a body plan table (Insert → Add Table) for the following animal phyla: Porifera, Cnidaria, Platyhelminthes, Mollusca, Annelida, Nematoda, Arthropoda, Echinodermata, and Chordata. Describe each phylum by identifying the following body plan features. Use Lesson 12 (Chapter 32) and Lesson 13 (Chapter 33) as a guide. 1) Symmetry: Asymmetrical, Radial, or Bilateral 2) Tissue type: Parazoa, Eumetazoa (diploblastic), or Eumetazoa (triploblastic) 3) Body cavity (if triploblastic): Acoelomate, Psuedocoelomate, or Coelomate 4) Developmental mode (if Coelomate): Protostome or Dueuterostome Note: Depending on the body plan, features 3 & 4 may not apply to specific phyla. * Please answer 3) and 4) ONLY. Thank you.

Which of the following is more closely related to Platyhelminthes: Arthropoda or Echinodermata? If you choose, you can say neither group is more closely related. Porifera Cnidaria Ctenophora Chordata Arthropoda Echinodermata Neither Hemichordata Echinodermata 10 Arthropoda Nematoda Annelida Mollusca Rotifera Platyhelminthes

Which of the following is the correct classification for the following invertebrate animal: This animal has a wedge shaped muscular "foot", and it is a filter feeder.  This animal is covered by two shells connected by hinge ligaments.   Question 22 options:   a)  Phylum Mollusca, Class Bivalvia   b)  Phylum Chordata   c)  Phylum Echinodermata   d)  Phylum Arthropoda, subphylum Hexapoda   e)  Phylum Platyhelminthes   f)  Phylum Echinodermata   g)  Phylum Annelida

Choose the locomotion mode of each taxonomic group (use once): Echinoidea [ Choose ] [Choose] Cephalopoda jointed legs Polychaetas muscular foot gliding on mucus muscular arms Ophiuroidea stream jet longitudinal muscles only Porifera tube feet Nematoda ciliated larvae, sedentary adult parapodia Arthropoda [Choose] Gastropoda [ Choose]

Create a cladogram summarizing the phylogenetic relationships among the different phyla. Phyla: Porifera             Cnidaria          Platyhelminthes          Annelida Mollusca   Nematoda   Arthropoda    Echinodermata     Chordata   Characters:  True tissues                    Blastopore forms the mouth         Blastopore forms anus Undergo ecdysis            Notochord                          Mantle and muscular foot   Water vascular system     Trochophore   Segmented jointed appendages    Chitinous setae                 Muscles and nerves            Triploblastic

You take a field trip to tide pools in Puget Sound and encounter all sorts of Animals. Please use the following descriptions of those adult Animals to determine which of the 9 major phyla each belongs. Has radial symmetry and two tissue layers:       ["cnidaria", "Mollusca", "Arthropoda", "Annelida", "Platyhelminthes", "Porifera"]  Has 6 jointed appendages and a chitinous exoskeleton:      ["cnidaria", "Mollusca", "Arthropoda", "Annelida", "Platyhelminthes", "Porifera"]  Has bilateral symmetry with a digestive sac and no coelom:     ["cnidaria", "Mollusca", "Arthropoda", "Nematoda", "Platyhelminthes", "Porifera"]  Has bilateral symmetry, an open circulatory system, a digestive tube, gills and a radula:  ["cnidaria", "Mollusca", "Arthropoda", "Nematoda", "Platyhelminthes", "Porifera"]  Has no true tissues and no body symmetry: ["cnidaria", "Mollusca", "Arthropoda", "Nematoda", "Platyhelminthes", "Porifera"]

What type of symmetry is seen in the roundworm? Does it exhibit cephalization? Ascaris is a parasite that swims constantly in human intestines. What structure protects the nematode from being digested? View the Trichinella slide. Trichinella is also a parasite. It can infect humans as well as other mammals like pigs, bears, and rodents. If untreated, it can lead to death.What mammal tissue does this roundworm infect?Draw a picture below of the Trichinella as viewed under the microscope. Although not mentioned on the website, if available view the live vinegar eel specimens. If there are no live specimens available, check out this you tube video instead: https://www.youtube.com/watch?v=UnjwvtFvyeQDescribe the movement of the vinegar eels.Do they have a complete or incomplete digestive system?
