Cnidarians
B for Plato users but it is a tissue level of organization
No. Cnidarians do not have teeth or any hard body parts.
The two types of true tissue found in cnidarians are the epidermis and the gastrodermis.
mesoglea.
Flatworms exhibit a bilateral symmetry and aacoelomate body plan, meaning they lack a body cavity and have a simplified organization with three tissue layers. In contrast, cnidarians have a radial symmetry and a body plan characterized by a gelatinous mesoglea layer, with two main tissue layers: the ectoderm and endoderm, and a central gastrovascular cavity. Additionally, cnidarians possess specialized cells called cnidocytes for capturing prey, which flatworms lack. Overall, these fundamental differences in symmetry, body organization, and tissue structure distinguish flatworms from cnidarians.

Cnidarians include jellyfish and corals. Cnidarians are less complex than annelids or mollusks because the latter have gills with many layers of tissue.
The stinging cells of cnidarians, called cnidocytes, are located on specialized structures called nematocysts. These nematocysts are found on the tentacles of cnidarians and are used for defense and capturing prey.
Some examples of specialized cells in cnidarians include cnidocytes (stinging cells) used for defense and capturing prey, sensory cells for detecting movement and light, and muscle cells for movement and contraction. Additionally, some cnidarians have specialized cells that secrete mucus or digestive enzymes for feeding.
They're called cnidocytes. ^^
Cnidarians have two cell layers with a jelly-like layer in between.
