The embryo is the young, developing plant contained within the seed of a plant. It consists of several important components:

  1. Radicle: This is the embryonic root of the plant, which emerges first from the seed during germination.

  2. Plumule: This is the embryonic shoot of the plant, which grows upward from the seed and develops into the stem and leaves.

  3. Cotyledons: These are the embryonic leaves of the plant, which provide nutrients and energy for the developing embryo until it can produce its own food through photosynthesis.

  4. Epicotyl: This is the region of the stem located above the cotyledons and below the first true leaves.

  5. Hypocotyl: This is the region of the stem located below the cotyledons, which develops into the lower part of the stem and the root system.

  6. Seed coat: This is the protective outer layer of the seed, which helps to prevent damage and drying out of the embryo.

All of these components work together to support the growth and development of the young plant as it emerges from the seed and begins its life cycle.
