DEVELOPMENT: Put these occurrences in the right order, and describe each situation. Cleavage, Embryo, Blastula, Blastopore, Zygote,
Micromere, Macromere, Blastulation, Gastrulation, Dorsal Lip, Blastocoel, Gastrula,
10. GERM LAYERS: During the process of gastrulation germ layers are created. What is a germ layer? ________________________________
________________________________________________________________________________________________________________
11. Describe the three germ layers:
i. Ectoderm: _____________________________________________________________________________________________________
ii. Endoderm: _____________________________________________________________________________________________________
iii. Mesoderm: ____________________________________________________________________________________________________
12. Which germ layer produces human skin? ___________________________ Which would produce a heart? ___________________________
which would create the lining of the stomach? _________________________________________
13. Some animals are diploblastic while higher organisms are triploblatic. What does this mean?

14. CAVITY DEVELOPOMENT: What is the coelom? ________________________________________________________________________
________________________________________________________________________________________________________________
15. (http://mansfield.osu.edu/~sabedon/campbl32.htm) In organisms that are triploblastic and contain the mesodermal layer of cells, this
mesoderm layer can interact with the endoderm layer in one of three ways to create three distinct groups of organisms. Describe them:
i. acoelomates: ___________________________________________________________________________________________________
______________________________________________________________________________________________________________
ii. pseudocoelomates: ______________________________________________________________________________________________
______________________________________________________________________________________________________________
iii. coelomates: ____________________________________________________________________________________________________
______________________________________________________________________________________________________________
16. THE GUT: (Still on Mansfield Site) The most primitive of organisms has one opening into their digestive system that acts as both the mouth
and the anus. When organisms developed a separate opening for the mouth and anus this was known as the gut. It arose twice in
evolutionary history to create two distinct groups of animals: Protostomes and Deuterostomes. Describe these two types of organisms and
explain which is “higher” evolutionarily. _________________________________________________________________________________
