The correct Answer is:
To solve the question, we need to identify the portion of the embryonal axis that is located above the level of attachment of the scutellum. Let's break down the steps: ### Step-by-Step Solution: 1. **Understanding the Structure of the Seed:** - A seed consists of several parts, including the seed coat, embryo, and cotyledons. The embryo is further divided into different parts: the plumule, radicle, and cotyledons. 2. **Identifying the Parts of the Embryo:** - The **plumule** is the upper terminal part of the embryo that will develop into the future shoot. - The **radicle** is the lower part of the embryo that will develop into the future root. - The **cotyledons** are the seed leaves that provide nutrients to the developing plant. 3. **Defining Key Terms:** - The **epicotyle** is the portion of the embryonal axis located between the attachment point of the cotyledons and the plumule. - The **hypocotyle** is the part of the embryonal axis below the cotyledons. - The **scutellum** is a specialized cotyledon found in monocots. 4. **Locating the Relevant Portion:** - The question asks for the portion of the embryonal axis that is above the level of attachment of the scutellum. This means we need to find the part that is directly above the scutellum. 5. **Identifying the Correct Answer:** - The portion of the embryonal axis located above the scutellum is referred to as the **epicotyle**. Therefore, the correct answer to the question is **epicotyle**. ### Final Answer: The portion of the embryonal axis above the level of attachment of the scutellum is called the **epicotyle**.
