What are three characteristics that all have in common?
All cnidarians live in water, have tentacles with specialized stinging cells called nematocysts, and have an internal sac for digestion which is called the gastrovascular cavity.

What are the three functions of the endoderm in coelenterates?
The endoderm in coelenterates functions in digestion, absorption of nutrients, and the production of gametes (reproductive cells). It lines the gastrovascular cavity and is responsible for carrying out these vital processes within the organism.
What are the three groups of cnidarians?
Three groups of cnidarians are 1. nematocyst 2. cnidocytes 3. gastrozooids
What are three major classes of cnidarians?
The three major classes of cnidarians are hydrozoans, jellyfish, and sea anemones and corals.
What are the few organs that Cnidarians have?
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.
What kind of structure do cnidarians have?
CnidariaCnidaria is a phylum containing some 11,000 species of relatively simple animals found exclusively in aquatic, mostly marine, environments. Cnidarians get their name from cnidocytes, which are specialized cells that carry stinging organelles. The corals, which are important reef-builders, belong here, as do the familiar sea anemones, jellyfish, sea pens, sea pansies and sea wasps. The names Coelenterata and Coelentera were formerly applied to the group, but as those names included the Ctenophores (comb jellies), they have been abandoned. Cnidarians are highly evident in the fossil records, having first appeared in the Precambrian era.
How many cavities in the pharynx?
There are three cavities in the pharynx: the nasopharynx, oropharynx, and laryngopharynx. Each cavity serves a specific function in the passage of air and food.
How many cavities are in your skull?
There are multiple cavities in the human skull, including the nasal cavity, oral cavity, and cranial cavity, which houses the brain.
How many life stages do cnidarians generally have?
Cnidarians have two cell layers with a jelly-like layer in between.
What are the three major body cavity?
Acoelomates, pseudocoelomates and coelomates
Are all bilaterally symmetric organisms triploblastic?
triploblastic organisms :1-Acoleomates: with no cavity, and three cell layers.2-coleomates : with cavity, and surrounding with ( mesoderms )3-pseudocoleomates : with cavity filled with fluid, and lined with ( mesoderms )
