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...
