The common term is pregnancy. The technical term is gestation.
From the time a fertilized egg is implanted in a mother's uterus until about the eighth week of pregnancy, the developing organism is called an embryo.
Genes control the sex of a developing embryo.
The developing embryo is connected to the placenta through the umbilical cord. This cord contains blood vessels that transport nutrients, oxygen, and waste products between the embryo and the placenta, facilitating crucial exchanges for fetal development. The placenta itself acts as an interface, allowing maternal blood to nourish the embryo while protecting it from certain substances. This connection is vital for the embryo’s growth and overall health during pregnancy.
to provide nourishment to the developing embryo in a seed
The developing embryo survives inside the mother's womb through a process called maternal-fetal circulation, where it receives nutrients and oxygen from the mother's blood through the placenta. Waste products and carbon dioxide are then removed from the embryo's blood and transferred back to the mother's circulation for elimination. The mother's body provides a protective environment and supports the growth and development of the embryo until birth.

The endosperm does. It acts much like yolk in an egg does for the embryo developing in the egg: provides the necessary nutrients for the developing embryo to grow from.
An embryo is the term used to describe a developing organism in its early stages of growth and development.
