eumetazoa उदाहरण वाक्य

"Pluripotent " cells, which can differentiate into other cell types, have not yet been demonstrated unambiguously in " T . adhaerens ", in contrast to the case of the Eumetazoa.
"' List of bilateral animal orders "'contains the Bilateria of the animal subkingdom Eumetazoa, divided into four superphyla, Deuterostomia, and the three Protostome superphyla, Ecdysozoa, Platyzoa and Lophotrochozoa.
On both sides of the septa are liquid-filled capsules that cause the mentioned separating structures to resemble synapses, i . e . nerve-cell junctions that occur in fully expressed form only in animals with tissues ( Eumetazoa ).
In both Homoscleromorpha and Eumetazoa layers of cells are bound together by attachment to a carpet-like basal membrane composed mainly of " type IV " collagen, a form of collagen not found in other sponges although the spongin fibers that reinforce the mesohyl of all demosponges is similar to " type IV " collagen.
Deuterostomia is a subtaxon of the Bilateria branch of the subkingdom Eumetazoa, within Animalia, and are distinguished from protostomes by their deuterostomic embryonic development; in deuterostomes, the first opening ( the blastopore ) becomes the anus, while in protostomes, it becomes the mouth . ( There are some occurrences of deuterostomy among Protostomes .)

Complicating the issue is the 1997 work of Lynn Margulis ( revising an earlier model by Thomas Cavalier-Smith ) that placed the Cnidaria and Ctenophora alone in the branch Radiata within Eumetazoa . ( The latter refers to all the animals except the sponges, Trichoplax, and the still poorly understood Mesozoa . ) Neither grouping is accepted universally; however, both are commonly encountered in taxonomic literature.
Some of the earlies lineages of multicellular animals with differentiated tissues ( see Eumetazoa ) that survived until modern times are jellies, comb jellies, corals, etc .; it would probably be safe to assume that the first multicellular animals with differentiated tissues were similar to some of those, and possessed similar body plan and organs . talk ) 22 : 25, 10 February 2015 ( UTC)
