What are the two tissue layers found in cnidarians?

Cnidarians possess two primary tissue layers: the outer epidermis and the inner gastrodermis. The epidermis provides protection and sensory functions, while the gastrodermis lines the digestive cavity and is involved in digestion and nutrient absorption. Between these layers lies a gelatinous substance called mesoglea, which provides structural support. This simple body plan facilitates their basic physiological functions.
