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
