The presence of extraembryonic membrane is a characteristic of amniotes as their development occurs on land either inside the egg or uterus whereas in amniotes their development occurs in water so they do not face the problem of desiccation, the supply of oxygen and removal of waste, therefore, extraembryonic membranes are not required by them. These foetal membranes in chick are developed from the extraembryonic blastoderm. There are four extraembryonic membranes namely- yolk sac, allantois, amnion and chorion. So take Extraembryonic Membranes quiz and increase your knowledge about the extraembryonic membrane.
