Study Guide – Introduction to Animal Diversity After attending the lecture and reading pages 654-655 and 658-661 in Chapter 32 you should be able to define and appropriately use the following terms: anterior arthropod bilateral symmetry bilaterian blastopore blastula body cavity body plan cell wall cephalization chordate clade cleavage coelom coelomate determinate cleavage deuterostome development ecdysozoans ectoderm endoderm Eukarya eumetazoan gastrula gastrulation heterotroph mesoderm metamorphosis protostome development pseudocoelomate radial cleavage radial symmetry spiral cleavage After attending the lecture and doing the assigned reading you should be able explain the following concepts and use this information to solve problems: 1. Detail the main features of animals that make them different than plants or bacteria – i.e. multicellular heterotrophs (although there are unicellular animals), diverse form, no cell

Unformatted text preview: walls, active movement, sexual reproduction, embryonic development. 2. Give the five key transitions in body plan. Explain why one might call them key transitions (i.e. what do they enable an organism to do that they couldnt do before). 3. Explain how each of these transitions are beneficial to survival of a species. 4. Compare and contrast asymmetry, radial symmetry, and bilateral symmetry. 5. Differentiate among acoelomate, pseudocoelomate, and coelomate organisms; indicate how they are evolutionarily related and give examples of each. 6. Understand the advantages of segmentation; give at least one example of segmentation in each of the coelomate phyla. 7. Differentiate between protostomes and deuterostomes. 1...
