YK.03. a EX 35 Taxonomy: The classification of organisms. Kingdom Æ Phylum Æ Class Æ Order Æ Family Æ Genus Æ Species • Latin is the language for taxonomy. Genera and species names must be typed in Italic font, or underlined by handwriting. Common Characteristics among animals: 1. 2. 3. 4. 5. 6. Multicellular Ingestive Heterotroph = (pp. 365) Eukaryotic = Capable of sexual reproduction Motile Lack of cell wall Phylum: Porifera: (porous organisms) • • • Symmetry = _________________ Commonly known as ________________. Mobility = _______________ Define function(s) of: • Choanocytes • Spicules o List three materials used to make spicules. • Amoebocytes • Mesenchyme Define location of: • Osculum • Spongocoel Feeding: • How do sponges feed? • Digestive method = __________-feeding, which is defined as – (pp. 366) Reproduction: Briefly explain about sponge reproduction: • Asexual reproduction • Sexual reproduction Classification: Poriferans are classified based on types of spicules. YK.03. a Phylum: Cnidaria: (from Cnidocyte Æ stinging) Structure • Symmetry = ____________ • Number of tissue (body) layers = _____, and they are called ______________, and _______________. • The ______________ is the filling layer between tissue layers. • Number of body plans = ____. • Explain about (summarize) each body plan. • • • Define polymorphism (pp. 369). How are the classes of cnidarians distinguished by? What are the classes under phylum Cnidaria? Feeding • What is the cindocytes? • What is the nematocysts? • Explain briefly about cnidarians’ feeding and digestive methods. Life cycle: • Summarize cnidarians’ life cycle (pp 369). Reproduction • Asexual – budding / fragmentation • Sexual – games (egg + sperm) Æ fertilization Æ zygote Class Hydrozoa: • Dominant body plan = ( • Hydra: o State habitat of Hydra. (pp. 370) o How many body plans? = ( ) o Body plan = ( ) ) • Obelia: o Why does Obelia typify the most hydrozoans? o Why do colonial polyps of Obelia are called polymorphic? o Be able to ID these polyps • Physalia: o Common name = o What unique about their body plan? • Gonionemus: o Which body plan that you observed this organism in the class? YK.03. a Class Scyphozoa: • Common name = • How did schyphozoans get their common name? Life cycle (fig 35.14) • Dioecious = (use Glossary of your lecture text book) • Dominant body plan = • Gametes Æ (haploid or diploid)? • Zygote Æ (haploid or diploid)? • Summarize life cycle of Scyphozoa Class Anthozoa • Common names (representatives) = • How many body plan(s) = ( ), and which is(are) ________________ • • Metridium o Mobility = o Fragmentation = o ID in the fish tank. Corals o Describe corals with following words: polyps, calcium carbonate, and cups. Latin words for the Biology 1740: • -cyte = some kind of cells. • gastro- = something to do with feeding and/or digestive part of organisms. • Ex- = out • Epi- = surface • Ect- = outer side • Meso = middle
