Explanation:

Most cnidarians have two layers of cells organized into some luck of tissues that have specific functions.

Cnidarians' body organization is simple: It is a hollow structure composed of two cellular layers: epidermis, which is the external layer, and gastrodermis that is the internal layer, formed by lining cells in the gastrovascular cavity. Between these two layers, place the mesoglea that varies from a thin non-cellular membrane to a mucous, fibrous, thick membrane with amebocytes.      

Epidermis and gastrodermis originate from two embryonic tissues, the ectoderm, and the endoderm, respectively.

The epidermis has five types of cells with different functions: epitheliomuscular, interstitial, cnidoblasts, secretors, and sensorial.

Gastrodermis is composed of cells such as nutritive cells, glandular enzymatic cells, secretory cells, and sensory cells.
