Placenta, amniotic fluid and umbilical cord.
A chicken egg is a round or oval body laid by the female chicken, which consists of an ovum surrounded by layers of membranes and an outer casing, which acts to nourish and protect a developing embryo and its nutrient reserves.
Fat in seeds is located in the portion of the seed called the endosperm. This is a lipoprotein complex that serves to nourish the developing embryo when the seed germinates.
The yolk sac arises from the ovum to nourish the embryo.
The yolk is there to nourish the growing embryo.
In double fertilization, one sperm reaches the egg and fertilizes it. This produces a diploid zygote that will grow into the plant embryo. A second sperm fuses with the endosperm nuclei in the embryo sac and produces the triploid endosperm. This will nourish the developing seedling.
Genes control the sex of a developing embryo.

to provide nourishment to the developing embryo in a seed
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 endosperm is in the gymnosperm 'naked seeds' and the angiosperm flowering plants. in gymno - haploid (n) gives nutrients to the embryo the only difference with the angiosperm is that its not haploid (n) but triploid (3n)
