BIOMOLECULES AND ENZYMES

Detailed explanation-1: -In certain species, including cereals, the endosperm stores reserves in the form of starch, proteins and lipids. The endosperm constitutes the edible part of the cereal seed and as such sustains directly or indirectly (via animal food) > 60% of human nutrition.

Detailed explanation-2: -The seeds which have endosperm are known as albuminous seeds. Endosperm is a special nourishing tissue present in the seed for the food storage. It will remain persistent till maturity. In albuminous seeds, food is stored in the endosperm so the cotyledons are small and thin compared to exalbuminous seeds.

Detailed explanation-3: -Seed storage reserves consist of complex molecules of carbohydrate, protein or lipid (Bewley and Black, 1994). During early post-germinative growth, storage reserves are broken down into soluble molecules such as sucrose which can be transported around the developing seedling.
