The course is almost over,
Classes will soon be done.
But now comes the hard part….
‘Cos the studying ain’t such fun!
We understand you’re nervous
We empathize with your ‘pain’
But don’t focus on that right now,
Just the grade you hope to claim!

Meet with TAs this week
(Be patient - there may be a crowd.)
Be prepared and on time to exams.
Don’t cheat, and make us proud!
So now I’ll get my act together,
And you can open your note book.
And let’s take a peek overall
At what deserves a second look!

Tho’ I talk fast in snooty British
There’s no need to panic yet
‘Cos the info is web-posted
In case there’s ‘stuff’ you forget!
Clues are scattered throughout my talk
So listen REALLY well.
Realize that I can’t go over EVERYthing
And the key I CANNOT sell……!
(Altho’ offers with 6-figures may be considered!)

There are fewer photos for the second half of the semester
on the web page.
This is because the phyla studied in the second half are
more easily recognized.

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 fromArthropoda – Protista (last half)and review fromMicroscopes – Annelida (first half)

Cheating on either final exam
• Any student caught cheating - or suspected to be, will be punished according to the rules of the Academic Honor Code (possibly thrown out of the course and even the university!)
• Take this warning seriously!
![Page 17: 00 Fall 05 Final Review - Florida State Universitybsc2011l/Fall 05 Final Review.pdf · 2005-11-30 · Subphylum Crustacea Largest class 3ORDERS Do not need to know!

The Point/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.
![Page 18: 00 Fall 05 Final Review - Florida State Universitybsc2011l/Fall 05 Final Review.pdf · 2005-11-30 · Subphylum Crustacea Largest class 3ORDERS Do not need to know!

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 3 ARTHRO…
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)

•Spelling: 1 letter will be over looked
2 letters - lose ½ point3 letters - lose 1 point
These rules only apply if 1 or 2 letters do notcreate another word that could mean that thestudent does not know the answer to the Q.

StaringUp or down - just not at your neighbor’s paper! = Cheating!
No talkingQuestions?- 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 languageThis is still cheating – just in silent mode!

End of the Exam…Hand in your response sheet to one of the TA/proctors.
Initial against your name on the sign up sheet.
Exit quietly DO NOT talk about the questions after you leave.
If you are caught sharing information about the exam, this will be considered cheating, (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!)
Grades should be posted (bulletin board) by Monday, Dec. 12 at noon.

•Protists are usually unicellular, but can be colonial
•Can colonize just about any moist environment
•Autotrophs (PHS), heterotrophs (phagocytosis), parasitic (malaria) even symbionts (termite & zooflagellates = mutualistic relationship)
•Reproduce asexually by binary fission or by budding
•Reproduce sexually by conjugation or by syngamy (gametes)
Protista Facto!

Study Ideas
Make lists of structures for common purposese.g. Book lungs, book gills, trachea and
spiracles and know the organisms that have them.
e.g. Malpighian tubules, Renette glands, protonephridia, Flames cells etc….
e.g. Statoblasts, gemmules, cryptobiotic eggs

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

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 medusaTurbellaria is the only free-living class in
Platyhelminthes; other two are parasiticOphiuroidea - no anusBrittle stars - no tube feetHolothuroidea - secondarily bilaterally symmetrical

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.”Epitoky, respiratory tree, mastax, trophi, trochus, septa, annulus, typhlosole, avicularia, crop, gizzard, parapodia, acicula, trochophore, …..
Sounds like a song from Nemo!
