BIO207 · UNIT 1: CLASSIFICATION OF ORGANISMS

4.0 Conclusion Classification is a system in which information on organisms is gathered, documented and stored in an orderly manner for easy reference. Animals with animal-like organisms are separated into two groups, invertebrates and vertebrates based on the absence or presence of a backbone.

What you should be able to do

  1. Explain the taxonomy of invertebrates.
  2. Describe the structure and level of organization of Mesozoa, Parazoa, and Metazoa.
  3. Classify organisms in a hierarchical manner.
  4. Apply the basic rules of the binomial system of nomenclature.
  5. Distinguish between diploblastic and triploblastic organization.
  6. Compare and contrast the characteristics of different invertebrate phyla.

Where it gets hard

The units students slow down on, and what makes each one heavy.

  • Module 1: Taxonomy Of Invertebrates

    Unit 3: A Systematic Approach to Lower Invertebrate Structure and Levels of Organization

    Requires understanding of complex terminology and hierarchical classification systems.

  • Module 2: The Structure And Level Of Organization of The Mesozoa, Parazoa And Metazoa

    Unit 1: Mesozoa

    The complex life cycles involving both sexual and asexual generations (metagenesis) can be difficult to grasp.

  • Module 3: Structure And Levels Of Organization Of The Platyhelminthes

    Unit 3: The Trematoda

    Requires understanding of the complex life cycles and parasitic adaptations of trematodes.
