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.
Cnidocytes are important because they contain stinging cells that cnidarians, like jellyfish and corals, use for defense and capturing prey. The specialized structure of cnidocytes allows them to quickly discharge venomous barbs when triggered by touch or chemical stimuli. This defense mechanism is crucial for cnidarians' survival in the marine environment.
True, tentacles are a common feature among cnidarians like jellyfish and sea anemones. These structures are typically armed with stinging cells called cnidocytes, which help cnidarians capture prey and defend against predators. Tentacles are used for a variety of functions including feeding, sensing the environment, and locomotion.

Cnidocytes are important to cnidarians as these are the stinging cells used to catch prey and defend from enemies. It is a toxin which can disable prey and provide protection from adversaries. This can be used as a harpoon, sticky surface or lasso type action.

Ctenophores are gelatinous creatures with rows of cilia for movement and lack stinging cells, while cnidarians have stinging cells called cnidocytes. Ctenophores also have a simpler body structure compared to the more complex body plans of cnidarians, which include jellyfish, corals, and sea anemones.
Stinging Cells
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.
Cnidarians all have stinging cells called nematocysts with which to catch their prey.
