How does oxygen and carbon dioxide get in and out of an amniotic egg?

The entire shell of the egg is covered in tiny little pores which allows for the passage of air and water into and out of the egg. The shell itself is recognized as a semi-permiable membrane. There is a chamber between the inner and outer soft membranes of the eggs (located just under the shell) that is actually hollow; it's an air cell. It grows as the chick does, surprisingly, but that's because as the chick gets older, it requires more CO2 to be transferred out of the egg, while allowing enough fresh oxygen to enter into the egg. The chick doesn't actually breathe into this chamber, the gasses are exchanged via an organ called the "allantois". This organ is responsible to handling liquid wastes and exchanging gases from the egg's air cell to the chick.

What is an egg that holds fluid that protects the embryo?
The answer is Amniotic egg.
What is the function of the amniotic sac?
The amniotic sac contains amniotic fluid, which has a number of roles which are important in the development of the fetus. # It acts as a thermal buffer and a shock absorber, and therefore protects the developing fetus. # The fetus drinks the amniotic fluid (this is called fetal respiration) and urinates into it. # It lubricates delivery of the fetus at term. # It is isotonic, so has the same water potential as the blood. # It is exchanged by the fetal skin up to 20 weeks of pregnancy. # It maintains a sterile environment for the fetus. # It aids development of the muscles and bones of the fetus. # Allows free movement of the fetus. # The amniotic sac acts as a hydrostatic wedge during the first stages of labour. Also, cells that are sloughed off from the fetus into the amniotic fluid can be cultured after an amniocentesis to look for genetic conditions such as Down's syndrome, however, this is not really a purpose of amniotic fluid.
What was first group of animals to use an amniotic egg?
the amniotic egg first evolved during the Carboniferous period. It evolved from amphibian ancestors and gave rise to the predecessors of reptiles and eventually gave rise to reptiles. not sure if that answers your question or not... be more specific next time.
What components make up life?
The frog life cycle is made up of many parts. First there is the egg then the egg hatches and out comes a tadpole. Later on the tadpole starts to grow legs and become a frog. Tadpoles eat the yolk of the eggs when the eggs hatch.
What would happen if fertilization does not occur?
After puberty, the ovaries release one egg each month alternatively. The sperms enter through the vagina, travel upwards to the oviduct where they encounter the egg. If the egg is fertilized, a zygote is formed. The zygote repeatedly divided to form the embryo. This embryo trickles down to the uterus. On the uterine wall, the embryo gets implanted. The embryo gets nutrition form a special disc shaped tissue towards the uterine wall called the placenta. It contains villi on the embryo's side and provides nourishment and oxygen from the mother's blood. Waste substances such as carbon dioxide and nitrogenous wastes are taken away from the embryo. After the 9 month gestation period, the child is delivered as a result of rhythmic contractions of the uterus.
Which of the following is true about the amniotic egg?
1. It resists drying out. 2. It permits oxygen and carbon dioxide to pass through
Why is it important that an amniotic egg shell is semi permeable?
Allows gases such as oxygen and carbon dioxide to pass through but prevents the embryo from drying out by holding water inside.
How is an amniotic egg important adaptation for reptiles?
The amniotic egg allows reptiles to reproduce on land, away from water.
What is amniote egg?
Reptiles, mammals, and birds lay amniotic eggs, which contain a yolk to nourish the developing organism. Eggs are used to protect the organism as it develops, and the egg also aids in gas and energy exchange.
Can carbon dioxide leave an egg shell?
No.
How does an embryo in an amniotic egg get oxygen?
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.
Why do gases travel across the shell of a reptile egg?
The embryo inside the egg is carrying out cellular respiration. In order for it to do that oxygen must be able to enter the egg and carbon dioxide must be able to leave.
Carbon dioxide sucks an egg into a bottle?
Yes it does
What is an example of an amniotic egg?
Chicken egg
Do turtles have amniotic egg?
No.
Which gases must travel across a reptile egg?
carbon dioxide
What is amniotic fluid in a chicken egg?
egg whites
