Exam 1 Review

Below is a link to the Jeopardy Game that we did today in SI. Don't forget that we have another exam review tomorrow at 11:30 in LL 130 (our classroom)

Below is a document that you all should be able to fill out (hopefully without looking in your notes or book). I will bring copies to the exam review tommorow.

Jeopardy Game

Below is a link to a Jeopardy Game that I created for this class, let me know if you can't access it

Label the Character

Label the picture below:

What phylum does this organism belong to?
What subphylum does this organism belong to?
What class does this organism belong to?


Label the picture below:

What phylum does this organism belong to?
What subphylum does this organism belong to?

Phylum Chordata - 5 Important Hallmarks

We have moved on to Phylum Chordata but before studying the characteristics of this diverse group make sure you are able to draw a phylogeny including all of the following:

Animalia (Metazoa)
Protostomia
Deuterostomia
Echinodermata
Asteroidea
Holothuroidea
Crinoidea
Ophiuroidea
Echinoidea
Chordata

After placing each of these group names at a node make a list of the unique characteristics for each node. An example would be under the node that contains Asteroidea you could list; madreporite on aboral side, podia contain suckers, open ambulacral groove. Hopefully you can do this activity without looking at notes or the book. If not do it again until you can.

*** If these characteristics seem foreign, you need to study more ***

5 Hallmark Characteristics of Chordata:

1.  Notochord - flexible, rod like structure that is replaced by a vertebrae in most vertebrates.
2. Dorsal Nerve Cord - dorsal to the digestive tract and hollow. The anterior end becomes enlarged to form the brain in vertebrates
3. Pharyngeal Slits (or Pouches) - slits evolved as a filter-feeding apparatus (still used for this in protochordates). Adaptations to this filter-feeding characteristic led to the evolution of a respiratory organ (internal gills) in aquatic vertebrates
4. Endostyle - secretes mucus that traps small food particles brought into the pharyngeal cavity. In ancestral chordates, endostyle and perforated (slits) pharynx work together to create an efficient filter-feeding apparatus. The thyroid gland in chordates is derived from the endostyle.
5. Postanal Tail - this tail along with muscle and stiffening of the notochord provided the motility for chordates. Its efficiency is later increased in fishes with the addition of fins.

Draw and Label

Below is an activity that may help you recognize germ layers (dermal layers), and structures.

1.      Draw a blastula

1.      label the dermal layers

2.      Draw a gastrula

1.      label the dermal layers and blastopore

3.      Draw an acoelom body plan

1.      label the dermal layers

4.      Draw a pseudosoelom body plan

1.      label the dermal layers

5.      Draw the begining of an enterocoelous coelom formation

1.      What germ layer produced the mesoderm?

2.      Does this plan create a Deutoerostome or a Protostome?

6.      Draw an eucoelom body plan ("eu" means true)

7.      What are the benefits of a true coelom?

8.      Draw an organism with spherical symmetry

9.      Draw an organism with radial symmetry

10. Draw an organism with bilateral body symmetry

1.      Where is the sagittal plane?

2.      What is the evolutionary advantage of bilateral symmetry?

11. What is an example of a unicellular organism?

1.      What domain does it belong to?

12. What is an example of a multicellular organism?

1.      What domain does it belong to?

13. What phylum is a sea urchin in?

1.      What are some unique characteristics of this phylum?

2.      What are the classes of this phylum?

3.      Draw a picture of one organism that belongs in each class

4.      Label the characteristics of the phylum in each picture (some may not have all the characteristics)

5.      Do any of these classes have their own unique characteristics? If yes, draw and label

14. Draw a Sea Star (big... we are drawing the water vascular system)

1.      Draw and label all of the following: (you should know these on your own)

1.      Ampulla

2.      Stone canal

3.      Lateral canal

4.      Ossicles

5.      Ring canal

6.      Ambulacral groove

7.      Podia

8.      Radial canal

9.      Madreporite

2.      Take a pencil or marker and show the path that the water follows to create suction in the tube feet
