Stem of barley shows

Options

A. Presence of collenchyma in hypodermis
B. Scattered vascular bundles
C. Presence of parenchymatous pericytes
D. Presence of parenchymatous pericytes.

Answer

**Step-by-Step Solution:**

1. **Identify the Plant**: The question asks about the stem of barley, which is scientifically known as *Hordeum vulgare*.

2. **Understand Vascular Bundles**: In plants, vascular bundles are the structures that contain the xylem and phloem, which are responsible for the transport of water, nutrients, and food.

3. **Analyze the Options**: The options provided are:
- Presence of cholangioma in hypodermis
- Scattered vascular bundles
- Presence of parenchymatous pericycles
- Presence of parenchymatous pericycles (repeated option)

4. **Correct Answer Identification**:
- The stem of barley is characterized by the presence of scattered vascular bundles.
- These bundles are found in the ground tissue of the stem and are numerous, with smaller bundles located towards the periphery and larger ones towards the center.

5. **Vascular Bundle Characteristics**:
- The vascular bundles in barley are described as:
- **Conjoined**: This means that the xylem and phloem are located together in the same bundle.
- **Collateral**: The phloem is located on the outer side and the xylem on the inner side.
- **Closed**: This indicates that there are no cambium layers present, which means that the vascular bundles do not contribute to secondary growth.

6. **Conclusion**: Based on the analysis, the correct answer to the question is that the stem of barley shows scattered vascular bundles.

**Final Answer**: The stem of barley shows scattered vascular bundles.
