Study Guide REMEMBER THE EXAM IS THIS TUESDAY! This exam covers the entire unit on invertebrates and vertebrates. Please be sure to review the various invertebrate groups (sponges, cnidarians, mollusks, worms, and arthropods) in addition to the various vertebrate groups (fish, amphibians, reptiles, birds, and mammals).
Key facts about INVERTEBRATES
Invertebrates DO NOT have a backbone. They are part of the ANIMAL KINGDOM. Characteristics of the animal kingdom: Multicellular and Heterotrophs All animals have shape. We describe this shape as symmetry. Animals are either asymmetrical, have radial symmetry or have bilateral symmetry. Asymmetrical: No symmetry is present. There is no way to divide the animal into equal parts. Below is an example of something that is asymmetrical. Notice that there is no way to divide the sponges into equal parts. The simplest invertebrates in the animal kingdom are the SPONGES. SPONGES: Symmetry: NO SYMMETRY! We call this asymmetrical Key facts: Adult sponges can not move. They are FILTER FEEDERS that use COLLAR CELLS to move water through their sponge bodies.

    23.1 – Sponges, Cnidarians, and Simple Worms
    • Sponges:
    > do not move
    > filter water to obtain oxygen and food
    > “skeletons” made of spicules
    > reproduce sexually and asexually
    • Cnidarians:
    > Examples: jellyfish, hydras, corals, sea anemones
    > Have a gut open to the outside > Have tentacles with nematocysts (stinging cells) • Flatworms: > Ex. fluke, tapeworm > Most are internal parasites > Can regenerate asexually • Roundworms: > Called nematodes > Most are parasitic > Most reproduce sexually > Some, like Ascaris, can cause diseases in animals and humans 23.2 – Mollusks, Annelids, and Arthropods • Mollusks: > There are 3 classes of mollusks: Bivalvia – clam, mussel, oyster Gastropoda – snail, slug; feed with a rough tongue called a radula Cephalopoda – squid, octopus, nautilus > They were the 1st animal to evolve nephridia to collect and discharge waste. > They have 3 basic body parts: head, foot, visceral mass.

The Biology of Sponges
Phylum Porifera, the simplest of the animal phyla, is an ideal group to begin studies of the animal kingdom. With an estimated 15,000 species diversity, sponges play important roles in aquatic ecosystems as bacterial filters. This program uses underwater photography, microscopy, animation, SEM, and timelapse microscopy to provide a colorful overview of sponge biology with an emphasis on structure, taxonomy, ecology and evolution. (15 minutes - #BO116) The Biology of Flatworms Flatworms, with their three clearly defined cell layers and bilateral symmetry, represent an important advance in early animal evolution. This program provides detailed observations on structure, behavior and life cycles of planarians and other free-living flatworms, some so small they can only be studied with a microscope (Class Turbellaria). It examines the bizarre life cycles of flukes (class Trematoda) and tapeworms (class Cestoda) with revealing shots of these parasites at home in the organs of their vertebrate hosts. (16 minutes - #BO116)

    Jellyfish are cnidarians which lack the polyp stage of the life cycle. Therefore, they are always in the medusae stage. They are considered plankton because they cannot swim on their ownthey are dependent upon the current to take them places.
  • The Moon Jelly Jelly fish are clear or translucent passive drifters. They are opportunistic feeders, but tend to be carnivorous. Their body consits of two layers, with the gut being the only cavity. Most people think of Jellyfish as toxic dangerous animals.

    Barnacles
  • Barnacles Barnacles cling to hard substratum and stay attached to them as they filter feed. Many are found in the intertidal region where pressure is high from predation, desecation, wave action, and competition for space.
  • Barnacles If you walk along the sea shore, you can find barnacles on almost any solid surface that gets covered by water. On rocks, dock pilings, boats, even mussels, you can find clusters of these hard, white, cone-like houses.

Since I give students their tests back the next day, I cannot give the same test to the absent students. Students will have to make up tests before school at 7:30, during their study hall period ( if it does not conflict with my teaming period), but not during class time or after school. There will be writing prompts this year on essay questions. Students will need to learn to create and keep a concept map (graphic organizer).

    exact number is not known and even our estimate are very rough. Animals
    range in size from no more than a few cells to organisms weighing many tons,
    such as blue whales and giant squid. Most animals inhabit the seas, with
    fewer in fresh water and even fewer on land.

They are determined by the total points accumulated by the end of that particular grading period, which is usually the semester. SCALE A = 90% AND ABOVE B = 80% - 89% C = 70% - 79% D = 60% - 69% F = 59% AND BELOW BIOLOGY: COURSE REQUIREMENTS DAILY SUPPLIES should be brought to class each day. These include: writing utensil, textbook, notebook, student planner. NOTEBOOKS are required and must be kept updated. They will be checked twice each nine weeks. They are graded on the following, and must be in order: 1. General course information 2. All handouts including notes, assignments, and tests, all arranged by chapter 3. Labs, in order ASSIGNMENTS must be turned in, for success in biology class, in a timely manner. Unexcused late work will recieve half credit. Extremely late work (beyond three weeks) will not be accepted. Make-up work is the students responsibility. TESTS will be given upojn completion of each unit of study. If absent the student must make up the test on their own time. These must also be done in a timely manner or a zero will be given.

    Click to view flyer at full size Click for details on how to register Rationale for Workshop A marine (saltwater) aquarium in the classroom can be a powerful tool to inspire interest in the sciences. It can provide a focal point for studies of biological diversity, chemistry, ecology, environmental biology, and other topics. A living, growing miniature marine ecosystem in the classroom also provides multiple opportunities for prolonged observations over months and even years, allowing students to observe growth and behavior of a wide diversity of organisms, giving students a familiarity with these organisms that is hard to achieve through other means. Though any aquarium can be a valuable teaching tool, marine aquaria offer particular benefits. There are many groups of invertebrates that have no terrestrial or freshwater representatives (e.g. echinoderms, tunicates, and others) or that are MUCH more diverse in the oceans than in freshwater (e.g. sponges, cnidarians, polychete worms, molluscs, crustaceans, and others). Similarly, a much greater diversity of algae grow in the oceans than in freshwater (for example, see
