Which tissue forms from both the uterine tissue and embryo tissue to support the fetus?

Explanation:
A placenta is formed when maternal uterine tissue (the decidua) and embryonic tissue (the chorion) come together to support the fetus. This organ enables the exchange of nutrients, oxygen, and waste between mother and fetus and also produces hormones to sustain pregnancy. The amnion is a membrane derived from the embryo, the chorion is embryonic tissue that contributes to the placenta, and the umbilical cord is the conduit connecting the fetus to the placenta. So the placenta uniquely combines both maternal and embryonic tissues to support fetal development.
