Porifera (sponges) have no specialized cells. To be diploblastic animal phyla must have a minimum of two cell layers referred to as ectoderm and endoderm. The absence of these cell types make it impossible for any members of porifera to be diploblastic.
They are animals having two germinal layers in the embryo, the outer ectoderm and the inner endoterm .Example of diploblastic animals are porifera and cnidaria.
Members of the phylum porifera are commonly called as sponges.
Al jellyfish are diploblastic; having two dermal lawyers. Ectoderm and endoderm.
porifera
Yes, all of them.
No they do not. I am not certain as to whether they have 0 or 2 germ layers but it is one of the two.
diploblastic have two body wall ectoderm and endoderm
Al jellyfish are diploblastic; having two dermal lawyers. Ectoderm and endoderm.
No, triploblastic.
A tapeworm is triploblastic, meaning it develops from three embryonic germ layers: ectoderm, mesoderm, and endoderm. This classification is typical of more complex organisms, including members of the phylum Platyhelminthes, to which tapeworms belong. In contrast, diploblastic organisms have only two germ layers.
Porifera are sponges.
spoges are diploblastic because they have radial symmetryone's having rad. sym. are diplo.and one's having bilateral are triploblasticThis is a true statement, but what we find in animal biology is that there are exceptions to most of the rules. Sponges, or the phylum Porifera do not have true tissues. They are metazoa at their cellular grade of construction, not eumetazoa. If you look at phylogenic tree, you will see that sponges are not directly related to cnidarians, which are radial symmetric and diploblastic. Some sponges are radial symmetric, however the class of sponges, demospongiae, have many species of sponges which have leuconoid body-plans, which are asymmetrical. These are mostly freshwater sponges. So therefore, sponges are not triploblastic or diploblastic, they are neither since they possess no true tissues.
