The following diagram shows an endospermic seed of Maize grain. Answer the following question:

In diagram the scutellum is represented by:

Z

The correct answer is Option (3) – Z

The scutellum is a specialized structure found in the embryo of grasses, including wheat. It is a single, large, shield-shaped cotyledon that is responsible for nutrient absorption during germination. It is located between the embryonic axis and the endosperm of the grain. The scutellum plays a vital role in providing nutrients to the developing seedling until it can establish its own photosynthetic capabilities. Therefore, in the given context, the large, shield-shaped cotyledon in the wheat grain is known as the scutellum.
