What is the anatomical structure of seed coat?
In the mature seed coat the outer fibrillar seed coat consists of the outer epidermis and hypodermis and separates easily to reveal the dense, smooth inner epidermis of the seed coat.
Which part of the seed is the seed coat?
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.

What are the three parts of a seed coat?
The three primary parts of a seed are the embryo, endosperm, and seed coat. The embryo is the young multicellular organism before it emerges from the seed. The endosperm is a source of stored food, consisting primarily of starches. The seed coat consists of one or more protective layers that encase the seed.
What is Epicotyl and hypocotyl?
An epicotyl, which extends above the cotyledon(s), is composed of the shoot apex and leaf primordia; a hypocotyl, which is the transition zone between the shoot and root; and the radicle.
What is seed morphology?
Seed morphology is the scientific analysis and description of the shape of seeds.
What is seed coat function?
The seed coat’s function is simultaneously to protect the embryo and to transmit information regarding the external environment. An impenetrable seed coat may help to keep the embryo safe, but at the same time it would exclude the sensing of environmental cues.
How seed coat is formed?
The seed coat, or testa, is derived from the one or two protective integuments of the ovule. The ovary, in the simplest case, develops into a fruit.
How do you plant Brassica seeds?
Brassica seeds are tiny and should be planted at a depth of about ¼ inch. Unless you are direct seeding a bed of baby greens, I recommend starting seedlings indoors 4 to 6 weeks before planting them in the garden.
How can you tell Brassica seedlings?
Kohlrabi—a Brassica—initially resembles seedlings of other members of this family, like broccoli, cauliflower, and kale. Until its first true leaves appear, it may be hard to recognize it! True leaves will have deeply serrated edges (more so than broccoli) and its leaves will be more pointed than rounded.
