The blastocoel has two main functions. 1.It permits cell migration during gastrulation.
2.It prevents the animal cells, destined to become ectoderm, from premature induction by the underlying vegetal cells into mesoderm.

Is the degenerating blastocoel visible in the frog gastrula?
no
Why blastocoel of blastula of frog called excentric?
It's because the cavity doesn't lie exactly at the centre, rather it lies in quite upper side.
What is the function of camouflage in the wild?
Camouflage is the process of blending into the background. It only works if the predator hunts by looking - animals who hunt by sound or smell are not fooled by camouflage! Many animals have color patterns which match the environment in which they live. If they freeze against this background, they blend in and are harder to see.

What is blastocoel?
A blastocoel is the fluid-filled cavity in the blastula.

What is the cavity within the blastula called?
blastocoel
What is a blastocoele?
A blastocoele is the fluid-filled cavity in the blastula.
The major body space in arthropods is the A. coelom B. pseudocoelom C. hemocoel D. blastocoel E. pseudocoelom?

What are the techniques to produce embryonic stem cells and embryonic germ cells?
Sacrifice a embryo at the blastocoel stage. Obtain the stem cells from the blastomere.
How does the morula stage of sea star development differ from the blastula stage?
The blastula is a single-layered ball with a fluid-filled cavity called the BLASTOCOEL in the middle (which the morula stage lacks). --Side note: The morula is a ball of cells about the same size as the original zygote and the large number of embryonic cells of the morula arrange themselves into a blastula, with the blastocoel in the middle.
Why blastocoel of blastula of frog called excentric?
It's because the cavity doesn't lie exactly at the centre, rather it lies in quite upper side.
What is produced by a zygote?
Zygote fungi is a phylum or ranking of fungi. It is also known as zygomycota. During sexual reproduction, zygote fungi produce resistant spherical spores.
What is a coelom body plan?
Coelom is a greek work literally meaning body cavity.A body cavity is a space between the alimentary canal and body wall. When it is lined by a layer of mesoderm, then it is called a true coelom. Depending upon this the animals are classified intoAcoelomates - Animals which don't have body cavity. Eg: PlatyhelminthesPseudocoelomates - Animals in which the body cavity is formed from embryonic blastocoel. This blastocoel acts as a body cavity in adults. Eg: AschelminthesSchizocoelomates - Animals in which the body cavity formed by splitting of mesoderm. Eg: Annelida, Arthropoda and MolluscaEnterocoelomates - Animals in which body cavity is derived from entero-mesoderm. Eg: Echinodermata, Hemichordata and chordata.
