Match List-I with List-II regarding the structure of a monocotyledonous seed. List-I List-II (A) Aleurone layer (I) Sheath enclosing the plumule (B) Scutellum (II) Sheath enclosing the radicle and root cap (C) Coleorhiza (III) Proteinous layer separating the embryo from the endosperm (D) Coleoptile (IV) Large and shield-shaped cotyledon Choose the correct answer from the options given below:
Options
- A(A)-(IV), (B)-(III), (C)-(II), (D)-(I)
- B(A)-(III), (B)-(IV), (C)-(I), (D)-(II)
- C(A)-(III), (B)-(IV), (C)-(II), (D)-(I)
- D(A)-(IV), (B)-(III), (C)-(I), (D)-(II)
Correct answer
C. (A)-(III), (B)-(IV), (C)-(II), (D)-(I)
Step-by-step solution
The correct matching of the structures of a monocotyledonous seed is as follows: Aleurone layer: It is the proteinous outer covering of the endosperm that separates it from the embryo. Scutellum: It is the single large and shield-shaped cotyledon of the monocot embryo. Coleorhiza: It is the undifferentiated sheath that encloses the radicle and root cap. Coleoptile: It is the sheath that encloses the plumule. Therefore, (A) matches with (III), (B) matches with (IV), (C) matches with (II), and (D) matches with (I). A
