Parts Labelled:
1. Embryo: This is the developing organism that is the product of fertilization. The embryo undergoes rapid cell division and differentiation to form tissues and organs.
2. Placenta: This is an organ that develops in the uterus during pregnancy. It serves as a connection between the mother and the developing embryo, providing nutrients, oxygen, and waste removal for the embryo.

Functions:
1. Embryo: The embryo is the developing organism that eventually grows into a fetus and then a baby. It is responsible for the growth and development of the new individual, including the formation of all organs and tissues.
2. Placenta: The placenta plays a crucial role in supporting the growing embryo. It allows for the exchange of nutrients, oxygen, and waste products between the mother and the embryo, ensuring the embryo receives all the necessary resources for growth and development. Additionally, the placenta produces hormones that help maintain the pregnancy and support fetal development.
In summary, the embryo is the developing organism while the placenta is the organ that supports its growth and development by facilitating the exchange of essential substances between the mother and the embryo. Both parts are essential for a successful pregnancy and the healthy development of the baby.
