Describe the progression and stages of embryo development from fertilization to an early embryo that has a fully formed neural tube. Include the following terms (at least) in your description: gastrulation, organogenesis (neurulation), zygote, cleavage, blastula, morula.

Examine the frog models 2-5 which represent the 2-cell, 4-cell,.. morula stages. During cleavage, the large zygote (fertilized egg), a single cell, divides (by mitosis) into two cells (2-cell stage); these two cells divide again yielding four (4-cell stage); these four cells divide again yielding eight (8-cell stage); and so on. After dividing a number of times, the embryo is a solid ball of cells, the morula. Just like in the starfish, a cavity (the blastocoel) then becomes visible in...

Draw and label early AND later stage blastulae, and answer the following questions. Blastulae (Label blastocoel, blastomeres) j) How does the size of the blastula compare with the size of the morula? k) How has the position of the cells change? 1) Why does the center appear to be lighter? Locate a later blastula stage. The cells of the blastula are now so small that it will be difficult to distinguish individual cells. The outer rim will appear to be...
