In monocot roots which types of vascular bundles are found

Options

A. Collateral, conjoint, and closed
B. Radial vascular bundles with exarch xylem
C. Bicollateral, conjoint, and closed
D. Radial vescular bundles with endarch xylem

Answer

### Step-by-Step Solution:

1. **Understanding Vascular Bundles**: Vascular bundles are arrangements of xylem and phloem in plants that facilitate the transport of water, nutrients, and food. In monocots, the arrangement of these bundles differs from that in dicots.

2. **Identifying the Structure of Monocot Roots**: In monocot roots, the vascular bundles are typically found in a specific arrangement. They are characterized by their radial formation, meaning that the xylem and phloem are arranged alternately.

3. **Types of Vascular Bundles in Monocot Roots**:
- **Radial Vascular Bundles**: In monocot roots, the vascular bundles are radial, which means that the xylem and phloem are arranged in such a way that they alternate with each other.
- **Exarch Xylem**: The xylem in monocot roots is of the exarch type, where the protoxylem (the first-formed xylem) is located towards the periphery, and the metaxylem (the later-formed xylem) is directed towards the center or pith of the root.

4. **Conclusion**: Therefore, in monocot roots, the vascular bundles are classified as radial vascular bundles with exarch xylem.

### Final Answer:
In monocot roots, the types of vascular bundles found are **radial vascular bundles with exarch xylem**.
