Dr. Presley Hints for Exam 1 Hints for Exam 1 1 HINTS FOR EXAM 2 Exam 2 date is ___________________. Check your syllabus and assignment calendars for the date. Exam 2 covers a lot of material on the entire animal kingdom (Chapters 31, 32, and 33), animal tissues, etc. (Chapter 40) and comparative physiology of gas exchange (Chapter 49). You will have become familiar with some of these critters in the laboratory. The work that you do on your handwritten Animal Kingdom Chart will help you. Remember that you will be able to use your chart for 20 minutes during the exam (you should read the entire test before using your chart for 20 min.). It is okay to make notes on your test booklet during this time. The following is a study guide to some of the most commonly missed questions over my 40 years of teaching biology. Study each of these. Contact your classmates for their suggestions of answers or study helps for these topics. 1. Animal Origins . Describe the general characteristics of animals. What is their cellular type? How do they obtain their food? Describe the hierarchy of structural organization in the simpler to higher animal groups. What two tissues are unique to the animal world? Name the principle type of life cycle among animals. What are the typical stages in an animal life cycle? What was the probable evolutionary ancestor of members of the animal kingdom? What characteristics are used to classify the groups of animals (consider the column labels for your chart)? Be able to give examples of animal groups and/or representatives that: are diploblastic or triploblastic, have radial symmetry or bilateral symmetry, have sac body plan or tube-within- a-tube plan, are acoelomates, pseudocoelomates or coelomates, are protostomes or deuterostomes, are segmented or unsegmented, invertebrate or vertebrate. Why is cephalization beneficial to animals? What is the definition of a coelom and why is it advantageous for the animal? What is a gastrovascular cavity and which animal groups have it? 2. Invertebrates . Define an invertebrate animal. Describe members of the phylum Porifera with respect to level of organization, symmetry, number of germ layers, and structures used in food getting and digestion. What are the functions of the amoebocytes? What is the function of spicules in the sponge? What are they composed of in the different groups of sponges such as the bath sponge? What is an hermaphrodite and generally how do they reproduce? What is the first animal group with true tissues? What are the three classes of the phylum Cnidaria? How many germ layers are there in a cnidarian? Why is the cnidarian life cycle not considered an alternation of generations as we have just studied in plants? What are the differences in structure and function of the polyp and medusa (--include differences in mesoglea layer)? Explain the functioning of a nematocyst. Is cnidarian digestion considered mainly intracellular
