rthe dicot root is identify by the presence of

Options

A. Ecarch xylem
B. 2-6 radial vascular bundles
C. `gt` 6 radial vascular bundles
D. Absence of pith and endodermis

Answer

### Step-by-Step Solution:

1. **Understanding Dicot Roots**: Dicot roots are characterized by specific structural features that distinguish them from monocot roots.

2. **Vascular Bundles**: In dicot roots, the vascular bundles are arranged radially. This means that the xylem and phloem are arranged in a circular pattern around the center of the root.

3. **Number of Vascular Bundles**: Dicot roots typically have 2 to 6 radial vascular bundles. Each vascular bundle consists of xylem and phloem tissues arranged alternately.

4. **Presence of Endodermis**: Dicot roots have an endodermis, which is a layer of cells that regulates the flow of water and nutrients into the vascular system.

5. **Absence of Pith**: In older dicot roots, the pith (the central part of the root) is generally absent.

6. **Identifying Features**: The key identifying feature of dicot roots is the presence of 2 to 6 radial vascular bundles.

7. **Conclusion**: Therefore, the correct answer to the question is that the dicot root is identified by the presence of 2 to 6 radial vascular bundles.

### Final Answer:
The dicot root is identified by the presence of **2 to 6 radial vascular bundles**.
