Cereal grain of botanical Karyps carypse called primary germ and endosperm of three parts and is comprised of the shell.

1. Raw sprouts:

Because the most important plant source of new production plants. Ajza’zyr is composed of:
A) radicle (radicula)
B) place or leaf bud (plumula)
C) Gyahk cotyledons (cotyledon scutellum)
D) Aptyl cylinder (cylindecepithel)
When the seeds start to sprout roots and change what appears in the form of chemical seed is produced. Gyahk cotyledons during germination and starch solution breaks and food grain supply is needed. Aptyl the long cylindrical cells made up of tasks that they are bringing food to the endosperm.

2. Endosperm (endosperm)

From different parts of cells, including cells of bonding agents such as starch and gluten Lrvn layer is composed. Endosperm during seed learned about 5/82-80 percent grain makes up. Endosperm starch in the form of regular and special forms are saved in different cereals, for example, wheat starch in the endosperm is more spherical and oval.
Endosperm cell wall thickness plays an important role in the value of properties and baking quality plays - Lrvn outermost layer of endosperm cells and endosperm cells around like sheath surrounding the works. Lrvn layer in the shell during mill, such as bran and flour (especially "Rdhay on) are separated. Bread flour protein value reduces. Lrvn layer about 7 percent of the cereal grain makes up.

3) shell (Bran)

La shell grains as a seed surrounded by a nearby guard and a member of bud material and food is stored. 2-layer shell of carpal Perry names Pericarp and testa (Testa) has been formed in the shell thickness can be extracted from flour as Mullah Hzh has a.
A - Pre-carpal or the first shell pericarp
The first sheet of thin shell called the epidermis epidermis epidermis made to form a protective layer, there is a combination of alcohol and wax that reduce the value of wheat to the bakery. B) The second shell or testa (testa) Is composed of two parts: 1 - brown layer from the layer 2 cell in very dense built their material is colored.
2 - layer between the testa and hyaline layer Hyalin Lrvn placed colorless.
4 - Krkha (Tarhay hair)
The upper grain cereals are Krkha. Color in different kinds of grain and wheat yellow or brown color is low.
On their profile can be diagnosed types of grain.
