vlc1500ParticipantExtraembryonic Membranes are vital to the success of reptiles, birds, and mammals. How does this have any relation to the egg and the embryo?

Your question is odd. Do you know what an extraembryonic membrane is?

ok this is what i meant to say……..
Extraembryonic Membranes are vital to the success of reptiles, birds, and mammals. Discuss with respect to the egg and the embryo. - February 18, 2007 at 11:05 am #69110dipjyotiParticipant
Extraembryonic Membranes
The embryos of reptiles, birds, and mammals produce 4 extraembryonic membranes:amnion
yolk sac
chorion, and
allantois
With these four membranes, the developing embryo is able to carry on essential metabolism while sealed within the egg. Surrounded by amniotic fluid, the embryo is kept as moist as a fish embryo in a pond. - March 7, 2007 at 1:32 am #69778vlc1500Participant
does anyone know exactly how the four membranes
amnion
yolk sac
chorion, and
allantoiswork to protect the embryo and egg?

I could answer this for you easily, but I think that you should Google each first and draw your own conclusions. Once you post them here, I will help you.
