List the three main parts of a seed and give the function of each

Embryo, Endosperm and Seed coat

Explanation:

The seeds for new life are found inside fruit. They contain everything necessary for the

growth and development of a new plant. The three primary parts of a seed are the embryo,

endosperm, and seed coat. The embryo is the young multicellular organism before it emerges

from the seed. The endosperm is a source of stored food, consisting primarily of starches.

The seed coat consists of one or more protective layers that encase the seed.
