Why coelenterates are called diploblastic animals?

Coelenterates are called diploblastic animals because:

i. Coelenterates animals have two layers of cells.

ii. One layer is ectoderm (outer) and other one is endoderm (inner)

iii. Both the layers are separated by a jelly substance called mesoglea.

iv. Due to the presence of two layers, they are called diploblastic animals.
