  • Classifying living things (18.1, dichotomous
    keys)
  • Part 2

Classification Review
Scientific Names Classification Cladograms
10 10 10
20 20 20
30 30 30
40 40 40
50 50 50
3
Scientific Names What are the two parts of a
scientific name? 10 pts
Genus and species
4
Scientific Names What is the two-word naming
system called? 20 points
Binomial nomenclature
5
Scientific Name What makes common names confusing
for classifying organisms? - 30 points
Common names can refer to multiple organisms
many names can be given for 1 species some
common names are ambiguous
6
Scientific Names Write the scientific name for a
species (your choice). 40 points
EX Homo sapiens
7
Scientific Names Give 2 characteristics of a
useful scientific name. - 50 points
Its used by everyone universally. It refers to
only 1 organism.
8
Classification Why do we need a system of
classification? -10 pts
To organize all living organisms into groups that
have biological meaning
9
Classification Who developed the first system of
classification? 20 points
Carolus Linneaus
10
Classification What is the genus of the domestic
cat Felis catus? 30 points
Felis
11
Classification Traditional (early) classification
was based primarily on what? - 40 points
Physical features
12
Classification Name the 7 levels of
classification we have today (in order from
largest to smallest) 50 points
Kingdom, phylum, class, order, family, genus,
species
13
Cladograms How is a cladogram different from a
dichotomous key? 10 points
Cladograms are based on evolutionary
relationships while dichotomous keys are based on
visible physical traits
14
Cladograms What is a derived character? 20
points
A derived character is a trait that arose in a
recent common ancestor and is not found in
earlier versions of the organism
15
Cladograms Name the derived characters in this
cladogram 30 points
Four limbs, amniotic egg, hair, specialized
shearing teeth, retractable claws
16
Cladograms What clade(s) has specialized shearing
teeth? 40 points
Clade Carnivora and Felidae
17
Cladograms Which clade includes all the others?
How do you know? 50 points
Clade Tetrapoda (having 4 limbs)

Animal Kingdom Review
  • Study Guide Questions

19
1. Invertebrates are animals that have no
  • Backbone

20
2. The distinguishing feature of acoelomates is
  • Bilateral symmetry
  • Pseudocoelom

21
3. Which of the following animals does NOT show
bilateral symmetry as an adult?

22
4. In which group of chordates did cartilage
first appear?

23
5. The fluid-filled space between an animals
digestive tract and its body wall is the
  • Body cavity

24
6. What germ layer develops into the
  • Outer layer of skin

25
7. Name 2 types of animals that show radial
symmetry

    hydras)
  2. Echinoderms (starfish, sand dollars, sea urchins)

26
8. Name two body plan characteristics shared by
all arthropods and chordates
Levels of organization Bilateral symmetry Three
germ layers True coelom Segmentation
and Cephalization
27
9. How has the body cavity evolved with the
evolution of worms?
  • Flatworm No body cavity (acoelom)
  • Roundworm Partial body cavity (pseudo-)
  • Segmented worm True body cavity (coelom)

Platyhelminthes Nematoda Annelida
28
10. Animals in the Phylum Porifera include
  • Chordates
  • Sea stars
  • Sea anemones
  • Sponges
  • D. Sponges

29
11. Most adult echinoderms show this kind of
symmetry
  • Radial

30
12. What is one way that cnidarians are different
from echinoderms?
- Levels of organization (echinoderms have
organs), of germ layers, type of body cavity
31
13. What type of body cavity do most groups have?
  • True coelom a body cavity completely lined with
    mesoderm (middle germ tissue layer)

32
14. List the 5 types of animals in Phylum Chordata
  • Fish
  • Amphibians
  • Reptiles
  • Birds
  • Mammals

33
15. List 3 traits that arthropods have that
cnidarians do not
  • Organs
  • Bilateral symmetry
  • 3 germ layers
  • True coelom
  • Segmentation
  • Cephalization

34
16.a) What characteristics have evolved in fish?
  • Vertebrae
  • Jaws, pairedappendages
  • True bone
  • Lungs!

35
16.b) What characteristics have evolved in
amphibians?
  • Four limbs

36
16.c) What characteristics have evolved in
reptiles?
  • Amniotic egg
  • Eggs dont develop in water
  • Dry, scaly skin

37
16.d) What characteristics have evolved in birds?
  • Endothermy
  • Feathers
  • Hollow bones

38
16.e) What characteristics have evolved in
mammals?
  • Endothermy
  • Hair/fur
  • Mammary glands

39
17. What characteristic do reptiles have that
amphibians do not?
  • Reptiles have lungs, amniotic eggs, eggs dont
    develop in water dry, scaly skin
  • Amphibians 1st stageof life- no lungs, eggsin
    water skin ismoist (no scales) go through
    metamorphosis

40
18. Which two major groups of fishes evolved from
the early jawless fish and still survive today?
  • Chondrichthyes(Cartilaginousfish - Sharks)
  • Osteichthyes(Bony fish)

41
19. The evolution of jaws and paired fins was an
important development in the rise of which group
of animals?
  • Sharks
  • (Cartilaginousfish)
  • ClassChondrichthyes

42
20. List 2 ways that bony fish differ from the
other two fish groups
  • Bony fish
  • 1. Have bone
  • (Sharks dont, jawless
  • fish dont)
  • 2. Have jaws
  • (Jawless fish dont)
  • 3. Have vertebrae
  • (Hagfish dont)

43
21. What adaptation enables birds to live in
environments that are colder than those in which
most reptiles live?
  • Endothermy
  • Feathers can use to
  • regulate body temperature

44
22. What evidence exists to indicate that
annelids and mollusks are closely related?
  • Levels of organization, body
  • symmetry, 3 germ layers, true
  • coelom, protostomes, and
  • cephalization

45
23. The only animal to have an asymmetrical body
plan is
  • Sponges

46
24. Which of the worm groups has the
characteristic of a segmented body?
  • Annelids

47
25. What was the 1st group of animals to have
cephalization?
  • Arthropods

48
26. What are 3 general characteristics that ALL
animals have?
  • To be included in the Animal Kingdom, an animal
    must
  • Be multicellular
  • Be heterotrophic (need food from others)
  • Lack cell walls

49
27. What are the two parts of a scientific name?
  • Genus and species

50
28. Which of these is the correct way to show the
scientific name for the brown bear?
  • ursus arctos
  • Ursus arctos
  • Ursus Arctos
  • Ursus arctos
  • d) Ursus arctos

51
29. List the 7 levels of classification from
largest to smallest
  • Kingdom
  • Phylum
  • Class
  • Order
  • Family
  • Genus
  • Species

52
30. What is the difference between using a
dichotomous key and a cladogram?
  • Dichotomous key for identifying an organism
    uses physical traits
  • Cladogram used to show evolutionary
    relationships uses more than just physical traits

53
31. In what ways are scientific names more useful
than common names?
  • Common names are bad because
  • They can refer to more than one species (American
    robin vs. European robin)
  • There can be multiple names for the same species
    (puma, mt lion, and cougar all talk about the
    same animal)
  • They can be confusing (sea horses arent really
    horses)

54
32. Who developed the first system of
classification, and what was it based on?
  • Carolus Linnaeus
  • Physical traits
