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).
