CLASSIFICATION and INTRO TO ANIMALS REVIEW Chapter 18 (pp 337-350) and Chapter 34 (pp 667-686)

1. A C ______is an ancestry diagram that shows evolutionary relationships between animals based on “shared derived characters”.

2. Greek philosopher who was the first person to classify organisms as plants or animals A ______

3. Type of cleavage pattern seen in protostomes in which cells “decide early” what they will become and the blastula “twists” as it divides = D ______S ______

4. Circulatory system in which circulatory fluid flows loose inside the body cavity = O ______

5. A ______structures (like a butterfly wing and a bird wing) may have a similar appearance and function but different embryological origin.

6. Circulatory system in which circulatory fluid (blood) is contained in vessels = C ______

7. Type of coelom (also called “true coelom”) in which the body cavity is lined on both sides by mesoderm = E ______

8. A P ______T ______is the diagram for the 6 Kingdom system based on MULTIPLE kinds of evidence that shows the evolutionary relationships thought to exist between groups of organisms.

9. A multicellular heterotrophic eukaryotic organism made of specialized cells that can move and reproduce is called an A ______.

11. Organism with DETERMINATE SPIRAL cleavage whose embryonic BLASTOPORE becomes its MOUTH = P ______

12. Type of coelom in which the body cavity is lined on only one side by mesoderm. = P ______

13. Organisms with I ______development start as an immature larval form and undergo metamorphosis to become adults.

14. B ______N ______is a system of naming that uses a 2 part genus and species name to identify organisms.

15. E ______are the only group of invertebrates we learned about whose embryos develop like those of higher animals. (They are deuterostomes).

16. All animals are H ______meaning that they obtain their food energy by consuming

other organisms. 17. The embryonic blastopore becomes the A ______in ECHINODERMS and ALL VERTEBRATES (higher animals). 18. H ______structures (like a bat wing and a human arm) originate from the SAME embryonic structures and suggest a recent common ancestor.

19. The indented area of an embryonic blastula that will become the digestive system in an organism is called a B ______

20. Type of body design with NO body cavity = A ______

21. C ______is the concentration of nervous tissue and sense organs in the anterior end of an organism.

22. A D ______is an organism with INDETERMINATE RADIAL cleavage whose embryonic BLASTOPORE becomes its ANUS.

23. P ______is the evolutionary history of a species or taxonomic group.

24. Germ layer that gives rise to MUSCLES and interior body linings = M ______

25. Organisms with D ______development are born or hatched looking similar to the parents only smaller.

26. C ______L ______was a Swedish naturalist who devised a system of grouping organisms into a hierarchy and giving them a 2 part scientific name.

27. The embryonic blastopore becomes the M ______in all invertebrates we will study except echinoderms.

28. M ______is the study of the internal and external structure and form of an organism.

29. When classifying plants, D ______is used instead of PHYLUM.

30. Type of nitrogen waste that is the most toxic and requires quick excretion and the most dilution. = A ______

31. A B ______is a hollow ball of cells formed when a zygote undergoes repeated cycles of cell division/mitosis.

32. Body system which deals with the outside body covering of an organism = I ______

33. Type of cleavage seen in deuterostomes = I ______R ______

34. Ammonia is converted into U ______(a safer form of nitrogen waste) and diluted by the kidneys to make urine in many vertebrates including you.

35. Type of symmetry seen in organisms (like a starfish) in which the body parts are arranged around a central axis

= R ______

36. U ______A ______is the form of nitrogen waste excreted by birds and reptiles that is the least toxic and needs the least amount of water to dilute. 37. N ______waste (ammonia, urea, or uric acid) comes from the break down of proteins by cells and is removed from the body by the excretory system because it is toxic (poisonous).
