Question

Germinated grams are considered highly nutritive. What is the reason for this belief?

Answer 1

Hint: In germination, an organism grows out from a seed or similar structure. It is used for the sprouting of a seedling from a seed which is of an angiosperm or gymnosperm. The growth of a seed from a spore takes place and the growth of a pollen tube from the seed of a plant.

Complete answer:
The seed contains endosperm which helps in the storage of food for the germinating seed and the seed gets hydrated during germination. The food gets transformed into active proteins, vitamins, fatty acids, and other nutrients in the endosperm. They become rich in carbohydrates and increase their amount. The complex food materials get converted into diffusible form when the seed starts germinating. The seed starts germinating when they are soaked in water and the metabolic activity in dormant seeds is initiated when they get hydrated in water. The endosperm persists in a mature seed stage as a storage tissue and the seeds are known as albuminous or endosperms. It is distributed between both endosperm and embryo in certain species. On getting maturation it stores fat and other main starches.

Additional Information: The endosperm is a tissue that is produced inside the seeds of most flowering plants and is followed by fertilization. It consists of three chromosomes i.e. it is triploid and gets surrounded by the embryo and provides nutrition in the form of starch. It also contains oils and proteins and makes the endosperm a source of nutrition in animal diet. Orchids have just like seeds which contain no endosperm in it. They are mycoheterotrophic in their early developmental stage and in some species, the endosperm does not develop. The grain consists of the nutritious part which is the seed and it’s the endosperm. Aleurone is the outermost layer of the endosperm which is present in all small grains and in many dicots it gets retained with transient endosperm. Its secrets, the amylase enzyme during germination which breaks, found the endosperm starch into sugars to nourish the growing seedling.

Note: The deterioration of a seed depends on its moisture content and temperature. Seeds are hygroscopic and are dry from the surface to the interior. Seed deterioration is irreversible and the seeds contain microorganisms.
