1-Are both the egg and zygote of a sea star the same size?
2-Do the cells of a two-cell sea star embryo differ in size?
3-Does the sea star embryo appear to be growing during cleavage?
4-What structures will the archenteron develop into?
5-What obvious visual change occurs in a frog egg upon fertilization?
6-How is the orientation of the blastocoel in an amphibian blastula different than that of a sea star?
7-What structures will form from the neural fold of the frog embryo?
8-In a chick embryo at gastrulation, what does the primitive streak indicate?
9-What are the segmented units that are visible along the dorsal axis of the 33 hour chick embryo?
10-The basic stages of development are quite similar for a wide range of organisms. How would you explain such consistency?
