What is the fate of the Blastopore in the frog embryo?
The blastopore expands into a circle (Figure 2.3C), and cells migrating through this circle become the lateral and ventral mesoderm. The cells remaining on the outside become the ectoderm, and this outer layer expands vegetally to enclose the entire embryo.Click to see full answer.

Then, what is the fate of Blastocoel in the embryo of starfish and frog? Amphibian blastocoel It was demonstrated in the frog embryo that the first cleavage furrow widens in the animal hemisphere creating a small intercellular cavity that is sealed off via tight junctions. As cleavage continues, the cavity expands to become the developed blastocoel.Furthermore, what is an embryo of a frog? The frog egg is a huge cell; its volume is over 1.6 million times larger than a normal frog cell. During embryonic development, the egg will be converted into a tadpole containing millions of cells but containing the same amount of organic matter. The upper hemisphere of the egg — the animal pole — is dark. Secondly, what is the fate of the Blastopore in the starfish embryo? gastrula in which the surface pushes into the interior at a point called the blastopore to form a tube that will become the digestive system. The blastopore is the future anus of the starfish.What is fate map of frog?A fate map is simply a topographical surface mapping of the blastula with respect to the ultimate fate of the various areas. The frog’s egg is very dark and it is difficult to apply vital dyes so that they will be visible on the frog blastula.
