The seed embryo in plants is essentially a tiny plant that has a root, a stem, and one or more leaves.
Seeds represent the embryonic stage of the plant life cycle. Most seeds are composed of three primary parts.
Key Components of a Seed
According to the definition, a typical seed consists of:
- Embryo: This is the vital component, the undeveloped plant itself. It contains the fundamental structures needed for future growth: a root (radicle), a stem (plumule), and one or more leaves (cotyledons, though the reference specifically states "leaves").
- Endosperm: This is the nourishing tissue that provides food for the developing embryo. It often contains starch, oil, and protein.
- Seed Coat: This protective outer layer encloses the embryo and endosperm, shielding them from environmental damage.
Think of the embryo as the miniature blueprint and starter kit for a new plant, tucked safely inside the seed, awaiting the right conditions to begin its journey of growth.
