Also remember there are two, short writing assignments, each worth 20 points.
Pick any topic in developmental biology (except your term paper topic) and learn more about it. Then write a two page paper and include all the sources you used (those can include any sources including web sites, newspapers, TV, etc). These are due anytime.

2. Chapter 8: Morphogenesis
Morphogenesis involves:
extracellular matrix
cell adhesion molecules
cytoskeleton

3. Chapter 8: Morphogenesis
Morphogenesis involves: cytoskeleton, cell adhesion molecules, ECM

4. Major components of the cytoskeleton:
Microfilaments
actin polymers
1) cell migration
2) cell shape changes
