Nematocysts or cnidocysts represent the common feature of all cnidarians. They are large organelles produced from the Golgi apparatus as a secretory product within a specialized cell, the nematocyte or cnidocyte.Nearly all (about 99 percent) cnidarians are marine species. Cnidarians contain specialized cells known as cnidocytes (“stinging cells”), which contain organelles called nematocysts (stingers).All Cnidaria are aquatic, mostly marine, organisms. They all have tentacles with stinging cells called nematocysts that they use to capture food. Cnidarians only have two body layers, the ectoderm and endoderm, separated by a jelly-like layer called the mesoglea. Most Cnidarians have radial symmetry.

What organisms have nematocysts?
nematocyst, minute, elongated, or spherical capsule produced exclusively by members of the phylum Cnidaria (e.g., jellyfish, corals, sea anemones). Several such capsules occur on the body surface.
Do cnidocytes contain nematocysts?
Cnidocytes contain large organelles called (a) nematocysts that store a coiled thread and barb. When hairlike projections on the cell surface are touched, (b) the thread, barb, and a toxin are fired from the organelle.
What are 5 characteristics of cnidarians?

Which statement about Cnidaria is not true?
Answer and Explanation: The option that is NOT correct is: (a) The adult body is bilaterally symmetrical. The adult cnidarians are not bilaterally symmetrical.
What is the function of nematocyst?
Abstract. Nematocysts or cnidocysts represent the common feature of all cnidarians. They are large organelles produced from the Golgi apparatus as a secretory product within a specialized cell, the nematocyte or cnidocyte. Nematocysts are predominantly used for prey capture and defense, but also for locomotion.

Do corals have nematocysts?
To capture their food, corals use stinging cells called nematocysts. These cells are located in the coral polyp’s tentacles and outer tissues. If you’ve ever been “stung” by a jellyfish (a relative of corals), you’ve encountered nematocysts.
Do Hydra have nematocysts?
In Hydra, four types of nematocysts are present: the small desmonemes, with a tightly coiled tubule used for prey attachment; the holotrichous and spineless atrichous isorhizas; and the large stenoteles, with a prominent stylet apparatus at the tubule base employed for piercing solid cuticle structures (8–10).
What is the difference between cnidocyte and nematocyst?
A cnidocyte is an explosive cell having within it a giant secretory organelle (organ) called cnida which is a characteristic of the phylum Cnidaria. A Nematocyst is a specialized sub-cellular organelle (part of the cell) present in cnidocyte.
What is the difference between cnidocytes nematocysts Cnidaria and nematocysts?
The main difference between cnidocyte and nematocyst is that cnidocyte is a type of cell that helps predation of cnidarians whereas nematocyst is an organelle consisting of a coiled, thread-like stinger.
How do cnidarians differ from all other animals?
Cnidarians are distinguished from all other animals by having cnidocytes that fire harpoon like structures and are usually used mainly to capture prey. In some species, cnidocytes can also be used as anchors.
Do all cnidarians have tentacles?
All Cnidarians have tentacles with stinging cells in their tips which are used to capture and subdue prey. In fact, the phylum name “Cnidarian” literally means “stinging creature.” The stinging cells are called cnidocytes and contain a structure called a nematocyst.
How do you identify a cnidarian?
The Cnidaria display two basic structural types: 1) the sessile polyp, that is more or less cylindrical and has the mouth at the free distal end, with a thin mesogloea; 2) the free swimming medusa, that is saucer- or bell-shaped, with the convex surface upward and with the mouth and surrounding tentacles at the under …
Which of the following is not a characteristic of the cnidarians?
Answer: *Cnidarians are NOT deuterostomes.
What characteristics account for the great success of cnidarians?
The success of cnidarians, judged by species diversity and distribution, can probably be attributed to their efficiency as carnivores. Cnidarians usually present a large body area, covered with nematocysts, to the water; small animals are paralyzed and trapped when they touch this surface.

What are the biological features of phylum Cnidaria?
Cnidarians contain specialized cells known as cnidocytes (“stinging cells”) containing organelles called nematocysts (stingers). These cells are present around the mouth and tentacles, and serve to immobilize prey with toxins contained within the cells. Nematocysts contain coiled threads that may bear barbs.
Which of the following are characteristics of cnidarians quizlet?
- aquatic; majority marine.
- Have dipoblastic tissues.
- Sac-like gut (gastrovascular cavity, incomplete digestive tract)
- Radial symmetry.
- Tentacles.
- Two lifecycle stages.
- Ciliated planula larva.
- Nerve net, non polarized.
