Contains a region called the hypocotyl: embryo

Explanation:

The seed is the first developmental stage in the sporophyte generation of the life cycle of angiosperm plants. This structure is composed of the endosperm, the embryo and the seed coat. The endosperm is a triploid (3n) tissue that nourishes the embryo during early growth. Moreover, the diploid (2n) embryo is the seed part that will become a seedling and eventually grow into a plant, with roots, stem, leaves and flowers. Finally, the hypocotyl is the small stem-like structure of a germinating seedling.
