What is a polyp? What is the relationship between corals and polyps

A general term for a variety of organisms in the class Coral. The body is cylindrical, with eight or more tentacles, and the tentacles have mouths. Mostly gregarious, combined into a group, it is a marine cylindrical coelenterate that feeds on the small plankton of the ocean, with food entering through the mouth and food residues excreted from the mouth.

As they grow, polyps absorb calcium and carbon dioxide from seawater, and then secrete limestone, which becomes their own shell. Whereas, corals are the secretions of polyps and make up the support structure of polyps.

Polyps are coelenterates, with an elliptical cylindrical body, with eight or more tentacles, tentacles ** have mouths and live in groups, combined into a group, dendritic, disc-shaped, block-shaped, produced in the tropical ocean, and live on the small plankton in the simple ocean, and corals are the secretions of polyps that constitute the support structure of polyps.

The polyp is a marine cylindrical coelenterate that automatically immobilizes to the calcareous of its progenitor corals at the white larval stage.

Coral is not an animal or a plant, coral is the shell secreted by polyps, the chemical composition of coral is mainly CaCO3, in the form of microcrystalline calcite aggregates, there is a certain amount of organic matter in the composition, the form is mostly dendritic, there are longitudinal stripes on it, each single coral cross-section has concentric circles and radial stripes, the color is often white, there are also a small amount of blue and black, the coral is not only like a branch, the color is bright and beautiful, it can be used as an ornament, and it also has high medicinal value.

The polyp is a marine cylindrical coelenterate that automatically attaches itself to the calcareous bone heap of the progenitor coral at the white larval stage.

The polyp is a marine cylindrical coelenterate, the food enters the debris from the mouth and is discharged from the mouth, it feeds on the small plankton in the ocean, has more than eight tentacles, tentacles ** have mouths, and is a social animal.

By absorbing calcium and carbon dioxide from seawater, polyps secrete limestone, which becomes their own shell. Whereas, corals are the secretions of polyps and make up the support structure of polyps.

The next day was Sunday, and Natalia woke up late. Yesterday she didn't speak all night, secretly ashamed of her tears, and didn't sleep well all night. She sat down at her little piano in her clothes, playing a few harmonies, barely audible so as not to wake Miss Boncourt, and then pressed her forehead to the cold keys, and remained there for a long time.

She kept thinking, not thinking about Luo Ting himself, but figuring out what he said. Her whole body and mind were immersed in her own thoughts. Sometimes, Volyntsev comes to her mind.

She knew he loved her. But her mind immediately threw him aside......She felt an inexplicable excitement. When she got up in the morning, she hurriedly dressed, went downstairs to greet her mother, and found an opportunity to go to the garden alone to ......It was a hot, clear, sunny day, although there were occasional showers.

Clouds that did not obscure the sun drifted slowly across the clear sky, and from time to time poured rain down on the fields without a trace. Diamond-like raindrops fell; Through the flickering rain curtain, the sun is beating happily; The grass that had been undulating in the wind just now stood still, greedily sucking the rain; Rain-soaked trees lazily shake their leaves up and down; The chirping of birds is accompanied by the crisp sound of rain. Smoke curled from the dusty road, and the rapid raindrops left small craters.

The rain stopped, the breeze blew, the grass changed its emerald green and golden colors again, and the damp leaves clinged together, leaving more gaps ......Everything around gives off a strong smell of freshness.

Corals and polyps are two different substances, the former is the corpse left behind by the polyp after death, and it is made up of calcareous; Whereas, a polyp is an animal.

Corals are not living things, polyps are living things.

1.The polyp is a marine cylindrical coelenterate that automatically attaches itself to the calcareous remains of its predecessor coral at the white larval stage, and grows in warm, shallow waters due to light and water temperature.

2.Corals are the shells secreted by polyps, the chemical composition of corals is mainly CaCO3, and corals are formed by the bones of polyps after death. It exists in the form of microcrystalline calcite aggregates, there is a certain amount of organic matter in the composition, the form is mostly dendritic, with longitudinal stripes on it, and each single coral cross-section has concentric circles and radial stripes, the color is often white, and there are a small amount of blue and black, the coral is not only like a branch, the color is bright and beautiful, it can be used as decorations, and it also has a high medicinal value put away.

Polyps are living beings, corals are not living things.

The polyp is a coelenterate in the ocean, which feeds on the small plankton in the ocean, and can absorb calcium and carbon dioxide from the seawater as it grows, and then secrete limestone, which becomes its own shell.

Coral is an abiotic phylum of cnidarians, including jellyfish, hydroids, soft corals, anemones and other animals. Corals are made by many polyps.
