Question

The monocotyledonous or the wheat seed has one large shield-shaped cotyledon which are known as
A. Coleoptile
B. Scutellum
C. Aleurone layer
D. Coleorhiza

Answer 1

Hint: The blooming plants or angiosperms capable of bearing seeds with a solitary cotyledon or undeveloped leaf are called Monocotyledons. However, the blossoming plants or angiosperms bearing seeds with two cotyledons or undeveloped leaves are called Dicotyledons. In general, the Monocotyledonous plants are additionally alluded to as monocots.

Complete answer:
The scutellum is believed to be an adjusted cotyledon or seed leaf. In grasses, this seed leaf never forms into a green structure yet serves to process endosperm and move supplements to the remainder of the incipient organism. The scutellum emerges from octant cells, which additionally add to the cotyledon.
The scutellum is available in monocotyledons endospermic seed. It is associated with the incipient organism by vascular tissue. The scutellum is straight facing the endosperm. When germination is started, the undeveloped organism begins to emit gibberellic acid (GA).
After 24 hours, the scutellum likewise begins to integrate GA. The GA triggers a combination of different chemicals by the aleurone layer. These proteins empower activation of the endosperm, and the items are consumed by the scutellum and passed to the creating undeveloped organism.
Hence, Option (b) Scutellum is a correct answer.

Note: The scutellum alludes to the identification of a slim cotyledon in monocots. It is thin with a high surface location and serves to ingest supplements from the endosperm during germination. It is essential for the structure of a grain and rice seed-the changed seed leaf. It is the rigid shield molded cotyledon. The tissue in a grass seed that lies between the undeveloped organism and the endosperm. It is the altered cotyledon of grasses, being particular for the assimilation and ingestion of the endosperm.
