Step by step
Solved in 3 steps
- Protozoans are usually separated into four groups based on their means of locomotion. Describe and contrast those means of locomotion.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 ScyphozoaLophotrochozoans add to their skeletal elements in abrupt rapid gradual invasive increments.
- Draw and label a hydrozoan colony life cycle showing gastrozoan and gonozoan polyps. Draw a medusa.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.Describe a potential advantage and disadvantage of the cuticle of ecdysozoans.
- There are Three classes in the superclass agantha.Name and discuss each class,give an example of each. Classes being : Ostracodermi Cephalasspidomorphi myxiniiGeneral characteristics of protozoans Internal and external structures Feeding strategies Locomotion Adaptations ReproductionPlacozoans are structurally simple. They have no mouth, gut, or nervous system and only a few distinct cell types. This simplicity is thought to be secondarily derived, because they have an asymmetrical adult stage. are composed of an upper and lower body surface that sandwiches a layer of contractile fibers. exhibit asexual and sexual reproduction. are sessile filter feeders. are found in tropical and subtropical oceans.
- Give possible ways of grouping protozoans other than the existing taxonomic classifications of protozoans. Outline the proposed classification.Describe the differences in the coelomic systems between Oligochaetes and Polychaetes. How do the differences in the coeloms relate to differences in locomotion? Which characteristics unify the lophophorates? Describe each characteristic and how it differs between the lophophorate phyla.Identify 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.
