Question
Chapter 32, Problem 2S
Summary Introduction
To determine:
Where the echinoderm would be placed in the animal kingdom.
Introduction:
Echinoderms are radially symmetrical, triploblastic, coelomate animals. They are mostly marine and contain water vascular system for locomotion. They have spines on their body, hence named echinoderms. The echinoderms include sea star, sea cucumber, sea urchin and others.

Create a concept map or an
illustration drawing for each
phylum (annelida,
Platyhelminthes, nemotod,
echinoderms, chordata) that will
help you classify invertebrate
animals into that group
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.
examine the morphology of a millipede and a butterfly.
What characters do they share? Notice how their bodies are divided into several specialized regions called tagmata. How did tagmatization contribute to the diversity of arthropods?

- Construct a character matrix by making observations on the different features of the following group of invertebrates. On the table, write 1 if the character is present in (or exhibited by) the group; 0 if absent (or is not exhibited).

Which one of the following would convince you that the organism is acoelomate? It responds to food by moving toward it. It is triploblastic. It has bilateral symmetry.

Based on the data that you recorded during this lab do you see a relationship between symmetry, cephalization, and number of germ layers? Can you tell what germ layer appears last?

How is the coelom used to differentiate among these different types of worms? Platyhelminthes exhibit a coelom only in the embryo, Annelids exhibit a coelom only in juveniles, and Nematodes exhibit a coelom in both embryos and adults. Platyhelminthes exhibit a coelom in embryos, Annelids exhibit a coelom only in juveniles and Nematodes lack a coelom. Platyhelminthes develop a coelom before the anal and oral pores develop, Annelids develop a coelom at the same time the anal and oral pores develop, and Nematodes lack a coelom. Platyhelminthes develop one coelom, Annelids develop two coelom, and Nematodes develop three coelom but then lose the one derived from mesoderm. Platyhelminthes lack a coelom, Annelids exhibit a coelom and Nematodes have a pseudocoelom.arrow_forwardCharles a Biology student in California has found at the beach an animal he cannot name.
