4. Characteristics of ALL Animals: 1.Are ____________________ cells have nucleus & membrane bound organelles 2. Are ____________________ get food from consuming other organisms 3. Are ____________________ made of many cells 4. Show __________________ different kinds of cells do different jobs EUKARYOTES HETEROTROPHIC MULTICELLULAR SPECIALIZATION

8. NO OPENINGS: Food enters through skin

9. Only one opening: FOOD IN and WASTE OUT through same opening Images from: http://www.geocities.com/animalbio/biology/DIGESTIO.gif

10. Two openings: FOOD IN at one end (mouth) WASTE OUT at other end (ANUS) Image from: http://www.geocities.com/animalbio/biology/DIGESTIO.gif

11. Two openings: Most efficient If food flows only one direction it allows for organ specialization (Different parts can start to do different jobs) Image from: http://www.geocities.com/animalbio/biology/DIGESTIO.gif

15. NITROGEN WASTE : _________________ Most TOXIC Must be removed QUICKLY Needs MOST water to dilute _________________ Made from ammonia by liver Less toxic than ammonia Can be stored if diluted with water (Needs less water to dilute than ammonia) _________________ LEAST TOXIC Can be stored if diluted with water (Needs LEAST amount of water to dilute) AMMONIA UREA URIC ACID

24. ALL WASTE is NOT THE SAME! DIGESTIVE WASTE NITROGEN WASTE WHERE ITS MADE? Body system used? In what form? made by cells from break down of proteins Handled by excretory system ammonia, urea, or uric acid Feces (poop) left over from undigested food Handled by digestive system

25. Kinds of Symmetry No symmetry Radial symmetry Bilateral symmetry

26. ___________________ No symmetry Doesn’t matter how you cut it; you never get 2 identical halves. ASYMMETRY Image from: http://mbgnet.mobot.org/salt/animals/sponges.htm

32. Data Table and Graph Surface area VolumeSA/VOL 1 2 3 4 5 6 7 8 9

33. Y= volume X= surface area

34. Y=s.a./vol X=radius

35. 3. EMBRYOLOGY Image from: http://calspace.ucsd.edu/virtualmuseum/litu/03_3.shtml 1.Where does BLASTOPORE end up? 2.What do embryos look like as they divide? 3.When do cells decide what they will be?

36. Image from: http://io.uwinnipeg.ca/~simmons/16cm05/1116/16anim3.htm EMBRYONIC DEVELOPMENT Becomes digestive system

37. EMBRYONIC DEVELOPMENT

41. All animals except sponges, jellyfish, anemones have 3 germ layers in their embryos Endoderm Mesoderm Ectoderm Muscle, excretory, bones, circulatory Digestive system, respiratory Outer skin, brain, nervous system

42. 1.Where does BLASTOPORE end up? Images modified from: http://io.uwinnipeg.ca/~simmons/16cm05/1116/16anim3.htm ANUS HERE POSSIBLY

43. What do embryos look like as they divide? Images from: http://www.zo.utexas.edu/faculty/sjasper/images/so28_04.gif SPIRALRADIAL CLEAVAGE CLEAVAGE

44. When do cells decide what they will become? Image from: http://www.rbej.com/content/figures/1477-7827-1-100-1.jpg ES= embryonic stem cells

45. Images modified from: http://www.rbej.com/content/figures/1477-7827-1-100-1.jpg Cells decide earlyCells decide later Removing cell causes death Removing cell OK DETERMINATE INDETERMINATE

46. THAT’S WHERE TWINS COME FROM!

47. ANIMALS Blastopore becomes MOUTH Blastopore becomes ANUS Decide very early (DETERMINATE) Decide later (INDETERMINATE) ALL INVERTEBRATES except ECHINODERMS ALL VERTEBRATES (Fish, amphibians, birds, reptiles, mammals) plus ECHINODERMS SPIRAL cleavage RADIAL cleavage PROTOSTOMES DEUTEROSTOMES

48. EMBRYOLOGY __________________ are the “exception to the rule”! They are INVERTEBRATES but their embryos act like _________________________ Echinoderms DEUTEROSTOMES Image from: http://www.bsac21.freeserve.co.uk/images/Critters/Starfish%20Bloody%20Henry.JPG

49. Types of Coeloms (See-Lums) No cavity (space) around organs Image from: http://io.uwinnipeg.ca/~simmons/16labman05/lb5pg10.htm ACOELOM = “without space”

50. FLATWORMS are ACOELOMATES!

51. Types of Coeloms (See-Lums) Space around organs but only lined with mesoderm on one side (lines body wall BUT NOT around gut) Image from: http://io.uwinnipeg.ca/~simmons/16labman05/lb5pg10.htm PSEUDOCOELOM

52. ROUND WORMS are PSEUDOCOELOMATES!

53. Kinds of Coeloms (See-Lums) COELOMATE: Body cavity (space) lined on BOTH sides by mesoderm Image from: http://io.uwinnipeg.ca/~simmons/16labman05/lb5pg10.htm EUCOELOM = TRUE COELOM = COELOM

54. COELOMATES ALL VERTEBRATES & SOME INVERTEBRATES ALL ANIMALS you will dissect this year are EUCOELOMATES!

55. 3 Types of Coeloms ectoderm mesoderm endoderm Image from: http://www.lander.edu/rsfox/310images/310bil5.jpg ACOELOM PSEUDOCOELOM COELOM

56. Advantages of having a COELOM (body space): In animals without a skeleton- Fluid in coelom space can act as a HYDROSTATIC skeleton In animals without blood vessels- Fluid in coelom space can circulate nutrients and oxygen to cells Provides space for internal organs

57. WHY is a COELOMATE the best? Digestive organ muscles and body wall muscles come from MESODERM in different places so organism can digest food and move at same time. Images from: http://www.lander.edu/rsfox/310images/310bil5.jpg http://www.okc.cc.ok.us/biologylabs/Images/Animal_Images/coelomate.gif

58. ________________ Concentration of nervous tissue and sensory organs in anterior end of an organism (head area) CEPHALIZATION

59. ________________ Repetition of body segments: as seen in earthworms (Annelids or segmented worms) and grasshoppers (Arthopods) METAMERISM
