BIOL 1202 : Biology Final Study Guide II
Document Summary
Identify the parts of and interpret a cladogram: explain the hierarchical classification system and list the different levels of the system, do keep pipes clean of gas. Chloroflexus: chemohterotrophs use chemicals as energy source (at least one organic source); many prokaryotes and protisits; fungi; animals and some plants. Identify the invertebrate animal phyla based on their derived characteristics: porifera (sponges) lack true tissues and are suspension feeders, platyhelminthes (flat worms) bilateral symmetry and cns. Identify the major groups of chordates/vertebrates based on their derived characteristics: phylum chordata, urochordata (tunicates) more closely related to other chordates than lancelets. Chordate characters most apparent during larval stage; larva used tail muscles & notochord to swim through water, which are absorbed once an adult: cephalochordata (lancelets) bladelike shape. As larvae, they develop a notochord, a dorsal, hollow nerve chord, pharyngeal slits, and post-anal tail: craniata (craniates) chordates that have a head. Neural crest give rise to teeth, bones and cartilage of skull.
