Embryo Seed Coat A seed coat protects the internal parts of a seed. The seed coat has two layers. The outer layer is thick and known as the testa. The inner layer is thin and known as tegmen. A thick seed coat protects the seed from sunlight and water. It prevents the loss of water and entry of parasites within the seeds.

Figure 26.3C. 1 26.3 C. 1: The fruit of the Aesculus or Horse Chestnut tree: These seeds are enclosed a protective outer covering called the seed coat, usually with some stored food. After fertilization and some growth in the angiosperm, the ripened ovule is produced. The formation of the seed completes the process of reproduction in seed.

Seed Growth. In angiosperms, the process of seed development begins with double fertilization and involves the fusion of the egg and sperm nuclei into a zygote. The second part of this process is the fusion of the polar nuclei with a second sperm cell nucleus, thus forming a primary endosperm. Right after fertilization, the zygote is mostly.

Essentially, a seed consists of a miniature undeveloped plant (the embryo), which, alone or in the company of stored food for its early development after germination, is surrounded by a protective coat (the testa).

Definition of Seed: A true seed is defined as a fertilized mature ovule that possesses embryonic plant, stored material, and a protective coat or coats. Seed is the reproductive structure characteristic of all phanerogams. The structure of seeds may be studied in such common types of pea, gram, bean almond or sunflower.

Parts of a Seed Diagram A typical seed consists of three main parts: 1) seed coat, 2) endosperm, and 3) embryo. 1) Seed Coat They are the protective outer covering of a seed that is usually hard, thick, and brownish in color. The seed coat is formed from the outer covering of the ovule called the integument.


Seed Germination Definition, Steps, & Factors Affecting Them

A seed, in botanical terms, is an embryonic plant enclosed inside its seed coat . Typically, the seed also has stored energy (proteins and carbohydrates) that are used by the seed during germination to establish itself when environmental conditions are favorable for growth. The stored energy is what makes seeds valuable for humans, too.
