Structure of a Seed
A typical structure of a seed and its parts are given below:
- The Embryo: The embryo is the young, developing plant contained within the seed and is protected by the seed coat. It comprises the plumule (embryonic shoot), radicle (embryonic root), and one or more cotyledons (seed leaves).
- The Endosperm: The endosperm is the tissue that surrounds the embryo and serves as a nutrient reservoir for the developing seedling. It contains stored carbohydrates, proteins, and lipids, providing energy and nutrients to support early growth and development.
- The Seed Coat (testa): The seed coat, also known as the testa, is the outermost covering of the seed. It serves as a protective barrier, protecting the embryo and endosperm from mechanical damage, desiccation, and pathogens.
Plumule of Seed
The plumule is the part of the embryonic structure found within the seed of a plant. It is a bud-like structure that serves as the precursor to the shoot system of the plant. The plumule in plants consists of the embryonic shoot apex, which contains meristematic tissue capable of giving rise to the plant’s stem, leaves, and other aerial parts. In this article, we will look into the meaning, location, features, and functions of plumule.
