The correct Answer is:
To answer the question "As compared to a dicot root, a monocot root has," we will analyze the characteristics of monocot and dicot roots step by step. ### Step-by-Step Solution: 1. **Understanding Root Structure**: - Roots can be classified into two main types: dicot roots and monocot roots. - Dicot roots typically have a specific arrangement of vascular tissues, while monocot roots have a different arrangement. 2. **Vascular Bundles**: - In dicot roots, the vascular bundles (which consist of xylem and phloem) are usually arranged in a ring and are fewer in number (typically 2 to 6). - In contrast, monocot roots have a higher number of vascular bundles. They can be described as exarch to polyarch, meaning they can have 6 or more vascular bundles. 3. **Secondary Growth**: - Dicot roots often exhibit secondary growth, which leads to the formation of annual rings and a thicker periderm. However, monocot roots do not show secondary growth, which means they lack annual rings and a relatively thicker periderm. 4. **Conclusion**: - Given the options provided: - **Inconspicuous**: Incorrect, as both types have visible structures. - **Annual rings**: Incorrect, as monocots do not form annual rings. - **Relatively thicker periderm**: Incorrect, as monocots do not have a thicker periderm due to lack of secondary growth. - **More abundance of xylem bundles**: Correct, as monocot roots have many xylem bundles compared to dicot roots. Thus, the correct answer is that a monocot root has **more abundance of xylem bundles** compared to a dicot root.
