Which membrane of the embryo gives rise to the placenta?

Solution
Placenta:
Between the developing embryo (fetus) and the mother's body, the chorionic villi and uterine tissue interdigitate to create the placenta, a morphological and functional unit that aids in the transfer of oxygen and nutrients to the fetus.
The embryo is also cleansed of carbon dioxide and excretory/waste materials.
The embryo's result is the placenta, which connects the embryo and the placenta.
The inner cell mass (embryo) divides into an exterior layer called ectoderm and an inner layer called endoderm shortly after implantation.
Between the ectoderm and the endoderm appears a mesoderm. In adults, these three layers give rise to all tissues (organs).
It's worth noting that the inner cell mass contains cells known as stem cells, which have the ability to give rise to all tissues and organs.
Chorion is the membrane from which the placenta is formed.
