Given below is the diagram of a typical monocot seed. Identify the parts labelled as A, B, C and D and choose the correct option.
Options
- AA- Plumule ; B- Endosperm ; C- Scutellum; D- Aleurone layer.
- BA- Aleurone layer; B- Endosperm; C- Scutellum; D- Plumule.
- CA- Plumule; B- Scutellum; C- Endosperm; D- Aleurone layer.
- DA- Scutellum; B- Plumule; C- Aleurone layer; D- Endosperm.
Correct answer
B. A- Aleurone layer; B- Endosperm; C- Scutellum; D- Plumule.
Step-by-step solution
Based on the longitudinal section of a typical monocot seed (like maize):
1. A represents the Aleurone layer, which is a proteinaceous layer that forms the outer boundary of the endosperm, separating it from the embryo.
2. B represents the Endosperm, which is the large, bulky tissue that stores food (primarily starch) for the developing embryo.
3. C represents the Scutellum, which is the single, large, shield-shaped cotyledon characteristic of monocot embryos.
4. D represents the Plumule, which is the embryonic shoot located above the embryonic axis.
Therefore, the correct identification is A- Aleurone layer; B- Endosperm; C- Scutellum; D- Plumule.
Answer: A- Aleurone layer; B- Endosperm; C- Scutellum; D- Plumule.
1. A represents the Aleurone layer, which is a proteinaceous layer that forms the outer boundary of the endosperm, separating it from the embryo.
2. B represents the Endosperm, which is the large, bulky tissue that stores food (primarily starch) for the developing embryo.
3. C represents the Scutellum, which is the single, large, shield-shaped cotyledon characteristic of monocot embryos.
4. D represents the Plumule, which is the embryonic shoot located above the embryonic axis.
Therefore, the correct identification is A- Aleurone layer; B- Endosperm; C- Scutellum; D- Plumule.
Answer: A- Aleurone layer; B- Endosperm; C- Scutellum; D- Plumule.
