If the mesentoblast cell is removed in the early embryonic development of protostomes what would be the fate of such animals ?

Text Solution

Verified by Experts

In the protostomes the mesentoblast cell of the early embryo divides to form mesodermal blacks between the ectoderm and the endoderm and replaces the blastocoel. The split that appears in each mesodermal black leads to the formation of Schizocoelom.
If the mesentoblast cell-is removed in the early embryonic development of protostomes it will case to no ceolome in their animals.
