Question

In the diagram showing the L.S of an embryo of grass, identify the answer having the correct combination of alphabets with the right part:

• A. A-Root cap; B-Coleoptile; C-Scutellum; D-Coleorhiza; E-Epiblast; F-Shoot apex
• B. A-Shoot apex;B-Epiblast;C-Coleorhiza;D-Scutellum;E-Coleoptile;F-Radicle
• C. A-Epiblast; B-Scutellum; C-Coleoptile; D-Radicle;E-Coleorhiza; F-Shoot apex
• D. A-Epiblast; B-Radicle; C-Coleoptile; D-Scutellum; E-Coleorhiza; F-Shoot apex

Answer 1

The correct option is D A-Epiblast; B-Radicle; C-Coleoptile; D-Scutellum; E-Coleorhiza; F-Shoot apex

The diagram represents a typical monocot embryo. The label A refers to epiblast. This is the remains of the second cotyledon in the monocot embryo. The label B refers to radicle. This is the root cap region. The label C refers to coleoptile. The shoot apex is protected with a shield called as coleoptile. The label D refers to scutellum. There is only one cotyledon and it is called as the scutellum. This is present in one side of the embryonal axis. The label E refers to coleorhiza. The root cap region is shielded with the help of coleorhiza. The label F refers to shoot apex. The shoot apex will develop to form the root.

Thus, the correct answer is option D.
