Verified step by step guidance

1. Understand that a seed is a plant's reproductive unit capable of developing into another plant.
2. Identify the three main parts of a seed: the embryo, the endosperm, and the seed coat.
3. The embryo is the young multicellular organism before it emerges from the seed.
4. The endosperm is a tissue produced inside the seeds of most flowering plants following fertilization, providing nutrition to the developing embryo.
5. The seed coat is the outer protective layer of the seed, which shields the embryo and endosperm from physical damage and disease.
