Question

is ctenophora is diploblastic or triploblastic?? no stupid answrs....

Answer 1

it is a Diploblastic , with ectoderm and entoderm , and a cellular mesenchyme , which gives, rise to the musculature (some researchers feel thatCtenophores are triploblastic , with a true mesoderm ). Adhesive structures called coloblasts (but no cnidoblasts or stinging cells as in Cnidaria ).

Answer 2

Biradially symmetrical, with an oral - aboral body axis .

Eight rows of ciliated "combs" or ctenes , controlled by an apical sense organ at the aboral pole.

Incomplete gut (mouth but no anus ).

No excretory, respiratory, or circulatory systems.

Diploblastic , with ectoderm and entoderm , and a cellular mesenchyme , which gives, rise to the musculature (some researchers feel that Ctenophores are triploblastic , with a true mesoderm ).

Adhesive structures called coloblasts (but no cnidoblasts or stinging cells as in Cnidaria ).

A diffuse nervous system consists of a nerve net, somewhat more specialized than that found in the Cnidaria .

A cydippid larval stage, monomorphic life cycle, never with a sessile or benthic stage.
