Question

Wheat germ is
A. Cotyledon
B. Endosperm
C. Embryo
D. Ovule

Answer 1

Hint: Wheat germ is part of wheat grain. It sprouts and grows into new plants. This part is rich in nutrients and protects cells from damaging.

Complete Answer:
- The wheat grains have three parts; The bran, endosperm and the germ. The bran is the skin, It has fibrous texture which is removed during the refining process.
- The most starch content is present in endosperm and the germ part of the wheat grain is an embryo and serves as a reproductive part where new wheat sprouts and it is used as whole wheat flour.
- Grem part is about 2.5% present in wheat grain.This part of wheat grain is rich in polyunsaturated fats, vitamins ,minerals and protein. Vitamin E in the germ helps in protecting cells from damage.
- Folic acid in the germ helps in making healthy cells which protects against some types of cancer;
- Magnesium keeps the heart, bone and the immune system strong. Thiamine is essential for the functioning of the heart, muscles and the nervous system.
- Phosphorus and calcium and helps in the growth and repair of all tissues. Zinc strengthens the immune system by fighting against viruses.

Therefore, the correct answer option is C Embryo.

Additional information:
- Germination is the process by which the dormant embryo of seed pauses it's metabolic activities and grows producing a seedlings.
- In wheat, hypogeal germination takes place, in which cotyledons remain below the soil.
- During this germination, the first radicle comes out and grows downward forming the root. Simultaneously, epicotyl which is the part of the embryo axis that lies above cotyledons, grows faster but only plumule comes out from the ground and develops into the shoot.

Note: Germ part is removed during white flour refinement but is used as whole wheat flour. Cereal grains components can be used as a source from which vegetable oil is extracted, or it is also used directly as a food ingredient.
