NEET BIOLOGY

Detailed explanation-1: -Monocotyledons (/ˌmɒnəˌkɒtəˈliːdənz/), commonly referred to as monocots, (Lilianae sensu Chase & Reveal) are grass and grass-like flowering plants (angiosperms), the seeds of which typically contain only one embryonic leaf, or cotyledon.

Detailed explanation-2: -Hence, the correct answer is ‘Cotyledons or Endosperm’

Detailed explanation-3: -Corn, wheat and rice, are examples of monocot seeds or monocotyledons. Embryos of a monocotyledonous seed possess only one large cotyledon called scutellum.

Detailed explanation-4: -Because of the presence of endosperm, monocot seeds are also known as albuminous seeds.

Detailed explanation-5: -In monocots, the single cotyledon is called a scutellum; it is connected directly to the embryo via vascular tissue. Food reserves are stored in the large endosperm. Upon germination, enzymes are secreted by the aleurone, a single layer of cells just inside the seed coat that surrounds the endosperm and embryo.
