No, triploblastic.
triploblastic : organisms which have three layers in the embryo : the ectoderm,mesoderm & endoderm
Triploblastic have three germinal layers and Diploblastic have two germinal layers
Yes, platyhelminthes are diploblastic, meaning they have two primary germ layers during embryonic development: the ectoderm and endoderm. They lack a mesoderm layer.
it is the most unnecessary thing. no one can answer that
triploblastic organisms :1-Acoleomates: with no cavity, and three cell layers.2-coleomates : with cavity, and surrounding with ( mesoderms )3-pseudocoleomates : with cavity filled with fluid, and lined with ( mesoderms )
Yes, a protostome is, and so is a deuterostome. Neither are diploblastic. This is mainly because of the developement of the coelem or body cavity. Just remember, both protosome and deuterostome require a three germ layer (that is a triploblastic cell) - ALWAYS
Yes. An example is a Nemathelminthes (roundworms)
It has always been a debate. Mesenchymal musculature in the middle tissue layer of ctenophores has invited speculation that they are triploblastic.
It is hypothetical name triploblasica .
flatworms are the only triploblastic organisms that lack a coelom
