CCP Biology Study Guide: Invertebrates

The test will consist of multiple-choice, matching, labeling a diagram of a worm and short answer responses to interpreting an experiment.

The textbook is organized as a systematic comparison, not as an organism to organism comparison, so information is spread around in chapters 25-29. Your notes, worksheets and reviewing the PowerPoints (available in the resources section of the web page) are more useful for this test.

Sponges and Cnidarians

You should be able to:

  • Define: invertebrate, parasite, cephalization and nematocyst.
  • Identify characteristics of organisms classified as animals.
  • Differentiate three types of symmetry animals have and give examples of phyla and/or organisms that show each.
  • Name the phylum that sponges belong to and list characteristics of them.
  • Describe characteristics of cnidarians include body form, and feeding methods.
Worms and Mollusks

You should be able to:

  • Define: hermaphrodite, dorsal, ventral, septum, setae, crop, gizzard, ganglion (cerebral), mantle, siphon and radula.
  • Compare acoelomate, pseudocoelomate and coelomate body plans, including advantages and evolutionary advancement.
  • Describe and compare characteristics of flatworms, roundworms and segmented worms, especially in terms of their role in the environment and importance to other organisms.
  • Label parts of an earthworm on a diagram and explain the function of those parts.
  • Describe general characteristics of mollusks and specific characteristics of the three classes of mollusks.
  • Explain the importance of mollusks to the environment and other organisms.
Arthropods and Echinoderms

You should be able to:

  • Define: exoskeleton, chitin, tracheal tubes, book lungs, gills, cephalothorax, thorax, abdomen, chelicerae, pedipalps, metamorphosis, pheromone, endoskeleton, water vascular system, tube foot.
  • Describe general characteristics of arthropods and specific characteristics of crustaceans, chelicerates (arachnids & horseshoe crabs) and insects.
  • Explain the importance of insects to the environment and other organisms.
  • Describe ways in which insects communicate with each other.
  • Describe general characteristics of echinoderms and specific characteristics of brittle stars, sea stars and sea cucumbers.
  • Explain the importance of echinoderms to the environment and other organisms.
