1 Answer

Answer :

(3) endosperm Explanation: The seed includes three primary regions: the embryo, nutritive tissue, and seed coat. Endosperm is a nutritive tissue that sustains the embryo and seedling. The endosperm may be consumed by the embryo as in many legumes, which use the cotyledons as a food source during germination.
