Detailed explanation-1: -Answer: The embryo is the part of the seed that develops into a plant. It contains the embryonic root (radical), embryonic stem (epicotyl and hypocotyl ), and one or two seed leaves (cotyledons). The endosperm contains the starch or stored energy for the developing embryo.
Detailed explanation-2: -The endosperm, cotyledons, and perisperm are all places where stored food may be found in seeds. During seed germination, the stored nourishment is utilized to sustain the embryo. The seed is called albuminous when the plant nourishment is stored outside of the embryo in a big endosperm.
Detailed explanation-3: -Seeds need oxygen so that they can produce energy for germination and growth. The embryo gets energy by breaking down its food stores.
Detailed explanation-4: -Hence, the correct answer is ‘Cotyledons or Endosperm’
