The vascular bundles in a dicot root are

Options

A. Radial and endarch
B. Conjoint and exarch Concentric and exarch
C. Concentric and exarch
D. Radial and exarch

Answer

**Step-by-Step Solution:**

1. **Understanding Vascular Bundles**: Vascular bundles are the structures in plants that contain xylem and phloem, which are responsible for the transport of water, nutrients, and food throughout the plant.

2. **Location in Dicot Roots**: In dicot roots, the vascular bundles are located centrally. This is in contrast to monocots, where the vascular bundles are scattered throughout the stem.

3. **Arrangement of Xylem and Phloem**: In dicot roots, the xylem is positioned in the center of the vascular bundle. The phloem surrounds the xylem, and they are separated by a layer of vascular cambium.

4. **Type of Vascular Bundles**: The vascular bundles in dicot roots are classified as radial. This means that the xylem and phloem are arranged in a way that they are positioned in a radial pattern, with xylem and phloem alternating.

5. **Conclusion**: Therefore, the vascular bundles in a dicot root are radial in arrangement, with xylem at the center and phloem surrounding it, separated by vascular cambium.
