The shell on an amniotic egg is equip with very small pores that allow oxygen to seep slowly into the embryo so that it doesn't suffocate.
There will be kind of pocket in the egg which contains enough oxygen for the chick to breathe in the egg for 21 days.
The egg shell has thousands of tiny pores that allow for air to enter and moisture to escape in very small amounts.
Really
The answer is Amniotic egg.
it provides protein to the embryo
The amniotic egg allows reptiles to reproduce on land, away from water.
A type of egg is composed of a protective shell and membranes that surround the developing embryo is an egg
Allows gases such as oxygen and carbon dioxide to pass through but prevents the embryo from drying out by holding water inside.
Oxygen can get to the embryo. Of course, it´s also the reason sea turtles lay their eggs on land, it works both ways.
THe shells of reptile eggs is porous - it absorbs oxygen through the membrane.
The amniotic egg has seven different parts that play different functions. The seven parts include the shell, albumen, chorion, yolk, allantois, ammunion and embryo.
It gives the embryo oxygen it needs to survive in the egg.
An amniotic egg is an egg which contains an amnios, a fluid filled membrane that surrounds the embryo to protect it. All reptiles, birds, and mammals produce amniotic eggs during reproduction. Those that give birth to live young, including mammals such as chimpanzees, develop an amniotic egg, although it doesn't have a shell, and retain the egg within the body until the offspring is born.
Amniotic membrane or amniotic sac, containing the embryo and amniotic fluid.
In a reptile egg there is a 'tube' that develops soon after the after the egg is laid, this allows the embryo to get oxygen through the egg skin, so if the egg falls into water, the oxygen supply stops and the embryo suffocates, same as if the egg is disturbed to much the embryo will be killed by the oxygen sack being drowned....
