ANSWER:-

The placenta is composed of both maternal tissue and tissue derived from the embryo. The chorion is the embryonic-derived portion of the placenta. It is composed of trophoblasts, which you may remember are the cells that made up the outer cell layer of the blastocyst. You may also remember that during implantation the trophoblasts multiply in number and extend into the uterine wall. They eventually form finger-like structures called chorionic villi, which are finger-like structures of the placenta composed of embryo-derived trophoblasts. The chorionic villi are surrounded by maternal blood which comes into direct contact with the embryonic trophoblast cells. The intervillous space is the part of the placenta that surrounds the chorionic villi and contains maternal blood.
