1. List the two functions of fertilization.
2.
Describe
the acrosomal reaction and explain how it ensures the gametes are conspefic.
3.
Describe
the cortical reaction.
4.
Explain
how the acrosomal and cortical reactions function sequentially to prevent
polyspermy.
5.
Describe
the changes that occur in an activated egg and explain the importance of
cytoplasmic materials to egg activation.
6.
Explain
the importance of embryo polarity during cleavage.
7.
Describe
the process of gastrulation and explain its importance.
8.
List
adult structures derived from each of the primary tissue layers.
9.
Using
diagrams, identify the various stages of embryonic development of an amphibian.
10. Distinguish between meroblastic cleavage and holoblastic cleavage.
11. List and explain the functions of the extraembryonic membranes in
bird and reptile eggs.
12. Compare and contrast development in birds and mammals.
13. Explain the relationships among polarity, cytoplasmic determinants
and development.
14. Describe how cell extension, contraction and adhesion are involved
in shaping the embryo.
15. Explain how interactions among the three primary tissue layers
influence organogenesis.
16. Explain the relationship between cytoplasmic cues and cell
determination.
17. Describe the importance of
cell location and orientation along the three body axes with respect to
polarity in the embryo, morphogenetic movements, and pattern formation.
