Many animals can be categorized as either protostomes and deuterostomes based on certain features of their embryonic development
. Determine whether each of the following terms applies to only protostomes, only deuterostomes, both protostomes and deuterostomes, or neither. Drag each item to the appropriate bin.
Protostomes: Protostomes may be defined as the organisms in which mouth develops first from the blastopore. These organisms shows the determinate and spiral cleavage. The coelum may be defined as the solid mass of the cell that are derived from the mesoderm.'
Deuterostomes: Deuterostomes may be defined as the organisms in which naus develop first from the blastopore. These organisms show indeterminate cleavage and coelum is derived from the archenteron.
Triploblast : Both protostomes and deuterostomes are triploblastic animals,
Why?: " Vestigial organs are physical structures that were fully developed
and functional in an ancestral group of organisms but are reduced
and unused in the later species."
