An amnion is the innermost membrane of the fetal membranes of reptiles, birds and mammals.
Amniotomy is surgical incision into the amnion.
The lighter appearance of the pro-amnion is due to its different composition compared to the amnion. The pro-amnion consists of a loose network of cells and fibrous material, which allows it to appear less dense and lighter in color. Additionally, the pro-amnion is more vascularized than the amnion, contributing to its lighter appearance.

Amnion is the membrane that covers the embryo. Chorion is the membrane that covers the amnion, the yolk sac, and the allantois. The space delimited by the chorion and the amnion is called amniotic cavity and it is filled with aminiotic fluid. The amniotic cavity has the functions of preventing desiccation of the embryo and of protecting it against mechanical shocks.

The embryo that does not have an amnion is the human embryo. It is a membrane that covers the embryo when first formed. Mammals, reptiles and birds have this feature.
There is no such thing as an "ovarian sac". The amnion is a membrane building the "amniotic sac" that surrounds and protects an embryo.
