Question

The single cotyledon in monocots is (1)Scutellum which is lateral in position (2)Aleurone layer which is terminal in position (3)Scutellum which is centrally placed (4)Epiblast which is haploid and lateral in position

Answer 1

Answer:

The scutellum is part of the structure of a barley and rice seed, the modified seed leaf. The scutellum can also refer to the equivalence of a thin cotyledon in monocots. It is very thin with high surface area and serves to absorb nutrients from the endosperm during germination. The scutellum is believed to contain an as yet unidentified protein transporter that facilitates starch movement from the endosperm to the embryo.

Thus, the correct answer is option B.
