Solved in 3 steps
- Name three disadvantages of sexual reproduction (relative to the asexual alternative). Name one advantage. Diagram the life cycles of a typical scyphozoan (e.g. Aurelia), a trematode, and a monogonontan rotifer, then compare and contrast the features of these life cycles. Be sure to emphasize where and how sexual reproduction, asexual reproduction and dispersal take place. Relate where sex and asex occur in the life cycle to the first part of the question.Contrast the pseudopodia of amoebozoans and forams.Cnidarians may exhibit an “alternation of generations” in their entire life cycle. Describe the “alternation of generations” using the life cycle of a hydrozoan, Obelia.
- Describe characteristics of phylum Platyhelminthes and its subgroups by discussing similarities and differences of 1)Morphological and anatomical features 2) life Styles 3)lifecycles and modes of reproduction of Turbellarians,trematodes and cestodesExplain the interaction of cuticle, body-wall muscles, and pseudocoelomic fluid in locomotion of nematodes.identify the distinguishing characteristics of the phylum Cnidaria.Describe the three in this phylum and give an example of each class. class being : Hydrzoa Anthozoa Scyphozoa
- Describe characteristics of nematodes and identify four parasitic nematodes.Describe a Phylum Porifera organism as: Parazoa or Eumetazoa Diploblastic or Triploblastic or neither Assymetrical or Radial Symmetrical or Bilaterially Symmetrical Aquatic or Terrestrial Acoelomate or Pseudocoelomate or Coelomate Protostome or Deuterostome or Neither Lophotrochozan or Ecdysosoan or NeitherIdentify what are described:1. The type of pseudopod exhibited by amoebozoans.2. The leading area for pseudopod movement in amoeba.3. The terminal region in amoeba responsible for exocytosis. 4. Causative agent of reptilian amoebiasis.5. Mass of naked multinucleate cytoplasm that serves as feeding stage in slimemolds.6. Aggregation of individual cells in cellular slime mold occur during thissituation.7. The feeding form of Entamoeba histolytica.8. Primary function of slime molds in the environment.9. Mode of nutrition among slime molds.10. This is another term for the pseudoplasmodium.
- Discuss the ecological importance of trematodes.Compare and contrast the body coverings of a free-living turbellarian, a monogenaen fluke, a cestode, and a nematode. Which problems does each solve or create? Be sure to consider locomotion, permeability, ciliation, and habitat, and to think of the entire life cycle.Contrast asexual reproduction in triclad turbellarians, Trematoda, and Cestoda.
