The two types of true tissue found in cnidarians are the epidermis and the gastrodermis.
Cnidarians have two cell layers with a jelly-like layer in between.
The presence of only two tissues layers makes cnidarians diploblastic. These tissues layers consist of an epidermis (outer layer) and a gastrodermis (inner gut layer). Mesoglea, a type of jelly-like substance is between these layers.
It's the jelly-like substance that is found between the two layers of cells in a cnidarian. The mesogea is not in all cnidarians though
Cnidarians - sea anemones, corals, jellyfish, box jellies, and hydrozoans - have two germ layers.
Hydra is in the phylum of the cnidarians which is a radical symmetry. so ectoderm, the outer layr which form the nerve sytem. Also, the endoderm, the inner layer are presented in the hydra.
Cnidarians.

The answer is probably sponges.
There is only a single layer of cells in onion tissue. However, sometimes the tissue can fold over itself and appear to have two layers.
