Digestion and absorption of food are major functions of gastrodermis .
The two types of true tissue found in cnidarians are the epidermis and the gastrodermis.
Epidermis is the skin....protection is its primary function
The function of the epidermis in the stem is to protect the underlying tissues.
protection
The epidermis is the outer layer of skin. It's function is to protect the inside of the body from germs.
Cnidarians have a simple body plan with a sac-like structure composed of three layers of cells: the epidermis, the gastrodermis, and the mesoglea. They possess specialized cells called cnidocytes that contain stinging structures called nematocysts, used for defense and capturing prey. Cnidarians also have a simple nerve net for coordinating movements and responses.
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.
Skin is respomsible for covering and holding the skelton in place
The body wall of a cnidarian consists of three layers, an outer layer known as the epidermis, a middle layer called the mesoglea, and an inner layer referred to as the gastrodermis.
In aquatic animals like cnidarians : mesogles helps in maintenance of buoyancy and transparency
the function of epidermis: in the lower part there is the sign,cellula,membrua, sinkline, and midrib in the upper part of epidermis there is also the sign cell, cellule, membrua, and sinotopilensicuaye and in wax layer is the botany crispifiedencius "crispifiedencius" is a kind of cell which leaves layer the insects into it. and the last layer is synocimprotocium membulare crisd.
The epidermis refers to the outer layer of skin (epi- from the Greek meaning "upon" and dermis from the Latinized form of the Greek word "derma" meaning "skin"). The gastrodermis refers to the inner layer of cells lining the gastrovascular cavity of Cnidarians (jellyfish, sea anemones, coral, etc.).
