This is a question our experts keep getting from time to time. Now, we have got the complete detailed explanation and answer for everyone, who is interested!
Hence, the solution that is right is “stinging cells.”
Which of the following does not exist in hydra endoderm?
-Stinging cells and cnidoblasts are not present in the gastrodermis of hydra, hence these cells are not present there.
In hydra, the cell known as the Gastrodermal cell contains what other cell?
In addition, the epidermis (also known as ectoderm) and gastrodermis (also known as endoderm) of Hydra contain myoepithelial cells, but the gastrodermis of N. vectensis is the only place where these cells can be detected. In anthozoans, the epidermis of the mouth is connected to a tubular pharynx, and the gastrodermis of N. crassa is connected to the pharynx.
What kind of cells make up the gastrodermis?
Cnidarians have an inner layer of cells that acts as a lining membrane for their gastrovascular cavity. This layer of cells is known as the gastrodermis. Moreover, the phrase can be used to refer to the same inner epithelial layer seen in ctenophores.
What role does the gastrodermis play in the body?
Musculo Nutritive cells. Note:- It is the endoderm that gives rise to the gastrodermis. The functions of secretion, digesting, and sensation are its primary roles. As a consequence of this, it possesses gland cells, digestive cells, and interstitial cells.
The cells that are not present in the gastrodermis of Hydra are known as

What does the term “cnidoblast cell” mean?
An explosive cell that can deliver a sting to other creatures, a cnidocyte (also known as a cnidoblast or nematocyte) contains one enormous secretory organelle known as a cnidocyst (also known as a cnida (plural cnidae) or nematocyst). This organelle is also known as a nematocyst.
Does Hydra have a nucleus of its own?
Large in size, epitheliomuscular cells can take on a columnar or cuboidal shape and always have a nucleus that is either positioned in the cell’s center or at its base. The nucleus is huge and has an uneven contour. It also contains material that is coarsely granular and a nucleolus that is massive and dense in the center.
What exactly does Hydra’s TS stand for?
Because it has two primary body layers, the term “diploblastic” best describes Hydra. Mesoglea, a material with the consistency of gel, is what separates each layer. The epidermis is the outermost layer, while the gastrodermis is the innermost layer because it borders the stomach. Both layers are referred to simply as the dermis. These two layers of the body are composed of cells that are not overly complex.
What distinguishing characteristics does Hydra possess?
This group of organisms shares the following characteristics: they live in aquatic environments, they possess tentacles, they have a single body entrance, they have two body layers, and they are, for the most part, radially or biradially symmetrical.
Which of these tissues does not exist in the Coelenterata?
Coelenterata, also known as Cnidaria, are organisms that have only an epidermis and a gastrodermis. In between these two layers is a jelly-like mesogloea that lacks structure to begin with but, as the animal evolves into a higher form, it becomes fibrous and possesses wandering amoebocytes.
Which of the following cell types can only be found in Hydra’s epidermis?
Germ cells and stinging cells are two types of cells.
Is there such a creature as the Hydra?
Hydra is a fictitious terrorist organization that appears in comic books published in the United States by Marvel Comics…. After World War II, Baron Wolfgang von Strucker took leadership of the organization and transformed it from a Nazi organization commanded by the Red Skull into a Neo-Nazi international crime syndicate. During that time, the Red Skull was the leader of the organization.
Can we see Hydra?
Although the northern hemisphere is the ideal place to view the constellation Hydra, also known as the sea snake, it is possible to see it between the months of January and May. It is visible at latitudes between 54 degrees and -83 degrees. It spans an area of 1,303 square degrees, making it the largest of all the constellations visible in the night sky.
Are the hydras able to see?
Even though it lacks eyes, the tiny freshwater hydra will roll itself up into a ball if it is suddenly exposed to strong light. Hydras are able to “see” light by utilizing two proteins that are extremely similar to those that are found in our own eyes. This discovery was made by David Plachetzki and his colleagues at the University of California, Santa Barbara.
What exactly is the purpose of the Hydra?
Hydra are sensitive environmental indicators and play an important part in the planktonic make-up of slow-moving water bodies, which are the types of bodies of water that they inhabit.
Which organism has Cnidoblast?
– Cnidoblasts are cells which grow into mature, specialized structures called cnidocytes. Cnidocytes are cells that are found in cnidarians (such as jellyfishes, sea anemones, corals, and hydrae), and they are responsible for the production of tubules that are threadlike and frequently toxic in order to trap prey and fend off attackers.
What are the four roles that nematocysts play in the body?
Nematocysts are utilized by organisms not only for the purpose of capturing prey and feeding on it, but also for defense, transportation, digesting, and a variety of other purposes [3,4].
Where exactly can one locate Cnidoblast?
Cnidoblasts are the hallmark of the Cnidaria phylum, which can be identified by their presence. They can be seen on the surface of the body as well as on the tentacles. These are functioning cells that may be found in the tentacles of jellyfish. They are able to project a thread-like structure either as a means of protecting themselves from other creatures or as a means of capturing prey.
In the context of Hydra, what role does Mesoglea play?
Hydra is made up of two cell layers separated by an acellular mesoglea in the middle. This mesoglea acts as both a skeleton to sustain the organism and a substratum for cell attachment. Both of these functions are performed by the mesoglea.
What are the key distinctions between the epidermis and the Gastrodermis?
The inner layer, which lines the stomach cavity, is known as the gastrodermis and originates from the endoderm. The outer layer, which originates from the ectoderm, is known as the epidermis and lines the outside of the animal.
What exactly do the cells that make up the epitheliomuscular junction do?
Epitheliomuscular cells make up cnidarians’ striated muscles, which are found in cnidarians. Cnidarian muscles perform two distinct roles: the first is contractile functions, which aid in the process of locomotion, and the second is the digestion of food within the cell. Because the muscles are organized in both longitudinal and circular patterns, a wide variety of motions can be performed by the body.
Is Hydra potentially dangerous to human health?
No, the stinging cells that they produce are not strong enough to hurt humans. If you make any attempt to touch them, they will swiftly roll up into a ball in order to protect themselves from being eaten by larger creatures.
