Question

The diagram given below is the V.S of maize seed. Identify the option where the alphabets are correctly identified.

• A. A = Aleurone tissue, B = Scutellum, C = Coleoptile, D = Plumule
• B. A = Scutellum, B = Endosperm, C = Coleoptile, D = Plumule
• C. A = Endosperm, B = Scutellum, C = Coleorhiza, D = Radicle
• D. A = Endosperm, B = Scutellum, C = Coleoptile, D = Plumule

Answer 1

The correct option is D

A = Endosperm, B = Scutellum, C = Coleoptile, D = Plumule

A = Endosperm, B = Scutellum, C = Coleoptile, D = Plumule.
In the seeds of cereals such as maize the seed coat is membranous and generally fused with the fruit wall. The endosperm is bulky and stores food. The outer covering of endosperm separates the embryo by a proteinous layer called aleurone layer. The embryo is small and situated in a groove at one end of the endosperm. It consists of one large and shield shaped cotyledon known as scutellum and a short axis with a plumule and a radicle. The plumule and radicle are enclosed in sheaths which are called coleoptile and coleorhiza respectively.
