Document Summary
No significance is placed on the order of any chapter objectives. Whenever possible and where appropriate you should always be prepared to give animal examples. Learning objective for all chapters on phylogeny: review figure 30. 7. Seta(e) a stiff hair-like structure, bristle, it can be found on the outside of the individual segments of an earthworm. Syncytium (syncytial epidermis) a multinucleated cell arising from the fusion of individual cells or the specialize connection via gap junctions as seen in the heart muscle for example. Objective 1: describe the distinguishing features, cells, and structure of sponges [poriferans] (knowledge/comprehension) A. habitat aquatic, mainly marine animals: cellular organization multicellular, but cells are loosely associated and do not form true tissues, parazoans no tissues (branch off to the sideoutgroup); polyphyletic origin - multiple ancestors. E. other gas exchange and waste removal by diffusion. Mesohyl gelatin-like layer between the outer and inner cell layers. Spongocoel central cavity where water passes into/accumulates.
