The cotyledon (or cotyledons)
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.

the developing embryo is nourished by yolk
Placenta is the organ that provides mechanical protection and nutritional support for the developing embryo. It connects the developing fetus to the uterine wall to allow nutrient and waste exchange between the mother and the fetus.

The endosperm provides nutrients for the developing plant embryo. It primarily stores carbohydrates, proteins, and fats to support the growth and development of the embryo until it can photosynthesize and produce its own food.
The egg white provides water and protein to the developing embryo, which are essential for its growth and development. It also acts as a protective barrier, shielding the embryo from potential external threats.
The purpose is to provide nourishment to a developing embryo in the seed.
The embryo receives nourishment from the mother through the placenta, which allows for the exchange of nutrients, oxygen, and waste products between the mother and the developing fetus. This nourishment is essential for the growth and development of the embryo throughout pregnancy.
Thin albumin provides hydration and facilitates gas exchange for the developing embryo, while thick albumin contains nutrients and provides protection. Together, they create a stable environment for the embryo to develop.
The embryo develops inside the uterus and receives nourishment through the placenta, which is formed from the tissues of both the mother and the embryo. The placenta allows for the exchange of nutrients, oxygen, and waste products between the mother and the developing embryo.
The placenta is the structure that allows the developing embryo to receive nourishment from the mother. It is formed during pregnancy and acts as a bridge between the mother and the developing fetus, providing nutrients and oxygen to support growth and development.
