3. Lab Practical Review Sessions Monday December 3, 2007 9 sessions to select from: 8:30a.m. to 8:30p.m. 28 students per session

4. Do not be late for the session you signed up for. (If you are you will have to stand by for the next available slot…) • Once checked in you can come and go as you please, but you cannot stay over your assigned time slot. • This is your opportunity to ask Q’s, see the specimens and dissections one more time….

5. Practical Exam Wednesday December 5, 2007 Take note of the exam time you signed up for & do not get your review & exam times mixed up!

6. Practical Logistics • 24 slots per session – Do not exceed 24 except by special permission (Director must sign off for additional seats) • If there is no room for you in a session – then you must make another choice or find a person willing to switch with you. • Students who have special needs must have their eligibility papers on file and MUST sign up for the last review and exam sessions.

7. Point Breakdown 25 Stations (3 Q’s per station)) 1 point per Q - 75 Points total ~1/3 TAXONOMY, IDENTIFICATION ~1/3 STRUCTURE/FUNCTION ~1/3 COMPARISIONS BETWEEN PHYLA Round 1 - 90 secondsper station Round 2 - 45 seconds per station

9. Take Note! • The final practical exam is cumulative. • Questions will focus on the last phyla studied but there will be questions on the material studied earlier in this course. • So, study hard from Arthropoda I – Protista.(last half) and review from Microscopes – Annelida. (first half)

10. Cheating on either final exam • Any student caught cheating - or suspected to be (acting in any way against our rules or in any way that makes us believe that cheating could be possible) will be treated according to the rules of the Academic Honor Policy. • Take this warning seriously!

11. The Practical Exam Grading Rules! • Capitalize taxa - ½ point WILL be deducted for not doing so. If you wish to use all capitals, make sure the first letter is most definitely TWICE as big as the rest.

12. For example: Taxonomic terms Non-taxonomic terms Arthropoda (perfect) asconoid (perfect) arthropoda (-1/2pt) Asconoid (no deduction) ARTHROPODA(-1/2pt) Mark the first letter as a capital by:1 ARTHROPODA 2 ARTHRO… or 3ARTHRO… Be especially careful when the first letter of a taxa looks the same regardless of upper/lower casing. Oligochaeta (perfect) simple (perfect) oligochaeta (-1/2pt)Simple (no deduction)

13. Spelling:1 letter will be over looked • 2 letters - lose ½ point • 3 letters - lose 1 point • These rules only apply if 1 or 2 letters do not • create another word that could mean that the • student does not know the answer to the Q. • rat cat • mesohyl mesophyll Cnidarian Plants

14. Words students frequently spell incorrectly Animalia rhynchocoel Arthropoda Scaphopoda Chondrichthyes schizocoely cilia scyphistoma cord Scyphozoa mesenchyme seminal (not Seminole!) notochord sinistral Opisthosoma spongocoel Osteichthyes symmetrical proboscis typhlosole

15. Exam Logistics Sign your sheet as soon as you get it. - this gives us permission to post your grade - give the last 4 digits of your ss# Fill out the top part to prevent confusion - your name, TA's name and your section number Fold your answer sheet in half lengthwise - keep the blank side facing youto act as a cover sheet. - open it only when you need to write on it. Circlethe 3 numbers of the questions where you begin. -Add the first one to the box on the blank side.

16. Scrap Paper - Your answer sheet can be used as to make notes Read each question - Be careful and give exact answers e.g. Do not give CLASS if the question asks for PHYLUM. Write legiblyor you risk losing points Do not give several answers - only the first one will be graded. Multiple choice questions When there is more than 1 correct answer give all of them to get the point/credit. Partial credit is never given for lettered responses. At the discretion of the grader (Moi!) it MAY be given for multiple word answers. Exam Logistics Contd.

17. Exam Logistics Contd. Hats Take off or wear them backwards please. Don’t touch! Microscopes - adjust only ocular or focal distance Specimens in jars - gently pick up jars to take a closer look, no shaking! Dissections Don’t move any of the pins or pointers. Oops! If you do think that you accidentally moved a pointer or a pin, raise your hand and tell a proctor/TA immediately.

18. Exam Logistics contd. Staring Up or down - just not at your neighbor’s paper! = Cheating! No talking Questions?- Raise your hand so the TA can come to you - don't wait until there are only 5 seconds left at the station. No sign language This is still cheating – just in silent mode!

19. End of the Exam… Step backfrom your response sheet and one of the proctors will collect it. Initial against your name on the sign up sheet. Exit quietlyDO NOT talk about the questions after you leave. If you are caught sharing information about the exam, this will be considered cheating, (attempted or accessory) and will be treated accordingly. Assuming that you are giving correct answers or clues….All you are doing is raising the average grade and ruining the exam for those scoring below the elevated average. (This could include YOU!) Gradeswill be posted (bulletin board outside CON239) ASAP

Worms, worms & more worms! 2nd half…. Thankfully a little more familiar!

21. Don’t forget the dissections……. and all those special little structures

22. Comparison ?’s A.How many of the following organisms are Deuterostomes? B. Give the Letter(s) of all organism(s) with incomplete digestive systems. C. How many phyla/classes are represented here? Read Q’s carefully Compare traits and group Phyla when studying!!!

25. Level of Organization Acellular Cellular Unicellular or Multicellular Tissue Organ What level of organization do we see in Kingdom Protista?

26. Level of Organization Cell(multi) - PhylumPorifera (unicellular) - Kingdom Protista Tissue- PhylumCnidaria Organ - PhylumPlatyhelminthesonward…

27. Symmetry RadialWhere do we first see this? Bilateral And this? Pentaradial And this?

28. Symmetry RadialPhylumCnidaria BilateralPhylumPlatyhelminthes onward… PentaradialPhylumEchinodermata except ………Holothuroidea which are secondarily bilaterally symmetrical

29. Digestive Systems Incomplete (No anus) Can you name 2 phyla? Complete (Have an anus) Can you name 2 phyla?

30. Digestive Systems Incomplete (No anus) PhylumCnidaria PhylumPlatyhelminthes If Q had been ‘Name 2 classes’….. Ophiuroidea & ? Complete (Have an anus) PhylumNemertina onward… (no anus in C. Ophiuroidea!)

34. Deuterostomes(2 Phyla) Radial cleavage, Enterocoelous Deuterostomes, Indeterminate “REDI” for anything! C PhylumEchinodermata PhylumChordata

35. Study Ideas Make lists of structures for common purposes, and learn which organisms posses which structures: e.g. Book lungs, book gills, trachea, spiracles papulae, lungs & gills. e.g. Malpighian tubules, Renette glands, protonephridia, Flames cells/bulbs etc…. e.g. Statoblasts, gemmules, cryptobiotic eggs

36. Be able to definethese terms and identify organisms that illustrate them • Cephalization Metamerizism • Tagmatization Homology • Serial Homology Polymorphism • Torsion Detorsion • Ecdysis This list is not exhaustive….add to it yourself!

37. Memory tip! • Learn the exceptions to the rules, the oddities (I love to test on those!) Make sure you understand why they are tricky though Fire coral is NOT a coral….it has a medusa Turbellaria is the only free-living class in Platyhelminthes; other two are parasitic Ophiuroidea - no anus Holothuroidea - secondarily bilateral symmetry

38. And finally… • Make a list of all of the unusual terms and structures you have come across and make sure you know where they fit in the “big picture.” Respiratory tree, mastax, trophi, trochus, septa, annulus, typhlosole, avicularia, crop, clitellum, gizzard, parapodia, acicula, proglottid, carapace, trochophore, ….. Sound like a song from Nemo?
