Where is the supply of nutrients in the seeds of beans, ash, almonds?

Beans, almonds and ash are flowering plants of the dicotyledonous class. The seeds of dicotyledonous plants consist of a seed coat and an embryo. Parts of the embryo – root, stalk, bud with leaves and two cotyledons. In many plants of this class, the supply of nutrients is found in large cotyledons. In some, the cotyledons are poorly developed and, then, the supply of substances is in a special tissue called endosperm. In the seeds of beans, almonds and ash, the supply of nutrients is contained in the cotyledons.
