A T.S shown conjoint, collateral, endarch and closed bundles scattered in a ground tissue. It is

Options

A. Dicot stem
B. Monocot stem
C. Dicot root
D. Monocot root

Answer

To solve the question regarding the transverse section (T.S) that shows conjoined, collateral, endarch, and closed bundles scattered in ground tissue, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Conjoined**: This means that the xylem and phloem are found together in the same vascular bundle.
- **Collateral**: In collateral bundles, the phloem is located on the outside (periphery) and the xylem is located on the inside (center).
- **Endarch**: This refers to the arrangement of xylem where the protoxylem (younger xylem) is located towards the center and the metaxylem (older xylem) is situated towards the periphery.
- **Closed Bundles**: These bundles lack cambium between the xylem and phloem, meaning there is no potential for secondary growth.

2. **Identify the Type of Plant Structure**:
- Given that the question describes a transverse section with the characteristics mentioned, we need to determine whether it is from a monocot or dicot stem/root.
- In monocot stems, the vascular bundles are typically scattered throughout the ground tissue, and they are usually conjoined, collateral, endarch, and closed.

3. **Evaluate the Options**:
- **Monocot Stem**: Fits the description of having scattered, conjoined, collateral, endarch, and closed bundles.
- **Dicot Stem**: Typically has vascular bundles arranged in a ring and may have open bundles.
- **Dicot Root**: Generally has a different arrangement of vascular tissues.
- **Monocot Root**: Usually has a different configuration compared to the stem.

4. **Conclusion**:
- Based on the characteristics provided in the question, the transverse section described is most likely from a **monocot stem**.

### Final Answer:
The T.S shown with conjoined, collateral, endarch, and closed bundles scattered in ground tissue is a **monocot stem**.
