Coelenterata (kolios = cavity / hallway, enteron = intestine) can be interpreted so colenterata hollow animals. Understanding colenterata more are animals that have a gut cavity. Some types of plants colenterata have similar shapes. Coloenterata is one class of colony-forming multicellular animals were still relatively primitive. Echinoderms (in Greek language, echino = hedgehog, derma = skin) is a group of animals that have triopoblastik selomata characteristic of their order in (endoskeleton) spiked which penetrate the skin.
Phylum Coelenterata are animals grand ridge elementary that have a large cavity in the middle of the body that serves grand ridge elementary as Intestines in animals high level. grand ridge elementary The cavity is called cavity gastrovaskuler. Radial Symmetry body and tentacles around grand ridge elementary the mouth which are used to capture and put food into his body. Vang tentacles equipped grand ridge elementary Knidoblas cells containing poison sting called Nematokis (characteristic of animal hollow).
Coelenterata is diploblastik animals because his body has two layers of cells, namely ectoderm (epidermis) and the endoderm (inner grand ridge elementary layer or gastrodermis). Ectoderm endoderm serves as a protective medium grand ridge elementary for digestive function. grand ridge elementary Gastrodermis cells bordering coelenteron or gastrosol. Gastrosol is shaped pouch digestion. The food that goes into gastrosol be digested by the enzyme released by cells gastrodermis. Digestion in gastrosol called extracellular digestion. Digestion results in gasrosol will be swallowed up by the cells gastrodermis to then further digested the food vacuole. Digestion in the digestive grand ridge elementary cells called i ntraseluler gastrodermis. Nutrients then circulated to other body parts as diffusion. Similarly, for oxygen uptake and disposal of carbon dioxide diffusion. Coelenterata have a simple nervous system, spread-shaped nets that serves to control movement in response to stimuli. The nervous system is contained in the mesoglea. Mesoglea is not a cell layer that exists between the epidermis and gastrodermis. Gastrodermis composed of gelatin material.
Coelenterata body shaped polyp, consisting of the legs, body, and mouth. Mouth surrounded by tentacles. Coelenterata that berbetuk medusa does not have the legs. Serves mouth to swallow food and remove leftovers because grand ridge elementary Coelenterata no anus. Tentacles used to catch prey and insert food into the mouth. On the surface of the cells of the tentacles are called Cnidocyte (knidosista) or knidoblas. Each capsule contains stinging Cnidocyte called nematokis (nematosista).
Polyps are Coelenterata form attached to the place of life. At the free end there is a mouth surrounded by tentacles. End of the body is used as a tool to attach to another.
Each individual Coelenterata have intestinal grand ridge elementary cavity. In this cavity in the form of particulate grand ridge elementary organic food, low level crustaceans, larvae of insects or other small animals digested. So the Coelenterata digestion occurs outside the cell or extracellular. Intestinal cavity Coelenterata branched or separated by a bulkhead. Through the intestinal branches earlier, distributed food substances. Therefore, the intestinal cavity Coelenterata called gastrovaskuler cavity. Coelenterata body size varies from a few millimeters up to 10 meters. Habitat found in seawater and freshwater. grand ridge elementary
Examples of the type of the class is the Hydra, which live in fresh water. The end of the lying mouth called oral tip while attached to the base called the aboral end. Called animal reproduction is by vegetative and generative. Another example is Obelia. grand ridge elementary
Most live in the form of medusa. Polyps form only at the level of the larvae. Examples of these types of classes are Aurelia sp. (Jellyfish ear) are often washed up on beaches. The larvae are called p lanula, then became polyps, grand ridge elementary called s kifistoma. From skifistoma formed medusa called Efira.
Not having the form of a medusa (throughout his life polyps). Examples of the type of the class is a sea anemone (Cribinopsis fernaldi). Having a simple breathing apparatus called grand ridge elementary s ifonoglifa.
Hydrozoa solitary life there (separately) and there are colonies (groups). Hydrozoa which has a solitary polyp shape, while colonizing the dominant form of polyp and medusa some kind of form. Examples of Hydra and Obellia.
Hydra body shape such as polyps, live in freshwater. Hydra body size between 10 mm - 30 mm. Food in the form of small plants and crustaceans are low. The lower part of the body forming a closed toe, point to attach to objects and to move. At the end of the
