Placenta belongs to both the mother and the fetus because they both contribute cells that lead to the growth of the placenta.

The placenta is an ephemeral (temporary) organ present in female placental vertebrates, such as some mammals and sharks during gestation (pregnancy), but a placenta has evolved independently also in other animals as well, for instance scorpions, and velvet worms.
The placenta is a fetomaternal organ that has two components, the fetal part (Chorion Frondosum) and the maternal part (Decidua Basailis).
The placenta is a primary site of nutrition and gas exchange between the mother and fetus.
By the beginning of 4th month the placenta has two components.
* Maternal Portion: Decidua Basailis
* Fetal Portion: Chorion Frondosum
Placenta is bordered on the Fetal side by Chorionic plate Maternal side by Decidual plate (decidua basailis)
Between the chorionic and decidual plates are intervillous spaces which are filled with maternal blood.
The placental barrier does NOT allow the two bloods from the mother and embryo to mix because if the blood types don't match then the baby will be destroyed..........

Both according to the site below.
The placenta is a fetomaternal organ that has two components, the fetal part (Chorion Frondosum) and the maternal part (Decidua Basailis).
By the beginning of 4th month the placenta has two components.
Maternal Portion: Decidua Basailis
Fetal Portion: Chorion Frondosum
Placenta is bordered on the Fetal side by Chorionic plate Maternal side by Decidual plate (decidua basailis)
Between the chorionic and decidual plates are intervillous spaces which are filled with maternal blood.
During the fourth and fifth months the decidua forms a number of decidual septa, which project into intervillous spaces but do not reach the chorionic plate. As a result of this septum formation the placenta is divided into a number of compartments or cotyledons. Since the decidual septa do not reach the chorionic plate, so contact between cotyledons is maintained.

it belongs to the fetus

The placenta is a fetal tissue (I think - I need to check up on it...)

sharing is caring. it comes naturally from the mother for the baby's use. its shows how muc mum cares abt the child.
