Question

what is the role of placenta in the development

of embryo​

Answer 1

The placenta plays a key role in the nutrition of the fetus. It mediates the active transport of nutrients and metabolic wastes across the barrier separating maternal and fetal compartments, as well as modifying the composition of some nutrients through its own metabolic activity.

Answer 2

Umbilical Cord. The placenta acts as a connection between the mother and the developing fetus. This connection is vital because without a placenta, a fetus would not be able to survive. It's the placenta that supplies the fetus with nutrients and removes wastes produced by the fetus.
