How does a pearl grow inside an oyster?

Answer 1

a piece of sand or particle gets caught inside and it secretes an enzyme to cover it up and it slowly adds layers to it over time making it get bigger and bigger

Answer 2

It is a small particle that has found it's way inside the oyster, While the oyster in very much Irritated by this particle being there it moves it around back and forth because it does not wish for it to be there. UNTIL it (small particle) forms into a Pearl this is how it is created. Anything other than this so called sand particle the oyster would spit it out. WOW It maybe to the oyster like something underneath our tong or on the back of our throat.

Answer 3

An oyster likes his home smooth and cozy. When a bit of sand gets inside the shell, he covers it with a layer of shell. If the sand is against the side of the shell, it is just buried there. If the sand is away from the shell, it is surrounded by shell material and grows into a pearl.

;-D There are both freshwater and salt water oysters. Pearls come in a lot of beautiful colors.

Answer 4

A small particle, like a piece of sand, gets into the oyster membrane and the oyster creates the pearl by making secretions around the particle as a defense mechanism. The longer the particle stays in the oyster the bigger the pearl.

Answer 5

an oyster secretes a solution to coat any foreign object that enters itside its shell. It is to protect it from infection or any other harm. Often it is only a pebble or particle of sand. It takes a long time to make a good sized pearl because several layers of coating have to gradually be applied. cultured pearls are pearls that are started by a person that inserts a "seed" or small piece of shell inside an oyster.

Answer 6

When a foreign object (sand, pebble, etc) gets into the shell, it creates an irritation that causes the oyster to coat it in the substance that makes up a pearl. It makes the irritation smooth but doesn't get rid of it so the oyster continues to put more coatings on it until it is removed.

Answer 7

A pearl forms when a speck of sand finds its way into the oysters' shell. This can cause infection and kill the oyster. The only defence the oyster has is to cover the sand with one of the few things it'd body produces, the stuff its shell is made of. it covers the sand all over and the shell stuff hardens and hey presto, you have a pearl!

Answer 8

A grain of sand gets into the oyster shell, this causes an irritation so the oyster starts coating the grain of sand with the same material as is on the inside of it's shell . It gets larger with time.

Answer 9

A piece of sand or other foreign object gets into an oyster. The oyster does not expell the object but reacts by coating it with its own excretions thereby creating the pearl.

Answer 10

A grain of sand creates an irritant to the oyster. So, the oyster secretes a calcite onto the sand to smooth it out. After layers of this secretion, a round object is formed.

Answer 11

Contrary to popular belief, pearls hardly ever result from the intrusion of a grain of sand into an oyster's shell. Instead, a pearl forms when an irritant such as a wayward food particle becomes trapped in the mollusk. The animal senses the object and coats it with layers of aragonite ("ah-RAG-uh-nite") and conchiolin ( "KON-kee-uh-lin"). These two materials are the same substances the animal uses to build its shell.

In most pearls, the mineral aragonite is arranged in sheets of flat, six-sided crystals. Between each sheet, the mollusk secretes a very thin layer of the membrane-forming protein conchiolin. This composite material is called nacre ("NAY-ker") or mother-of-pearl. The crystalline structure of nacre reflects light in a unique way, giving so-called nacreous pearls their high luster. In contrast, some pearls are not nacreous and instead have a low-luster, porcelainlike surface. The needlelike crystals of aragonite in these pearls are arranged perpendicularly or at an angle to the surface of the pearl.
