which of the following ch aracters is not found in the transverse section of monocot stem

Options

A. sclerenchyma bundle sheath
B. lysigenous cavity
C. sclerenchymatous hypodermis
D. starch sheath.

Answer

To determine which character is not found in the transverse section of a monocot stem, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of Monocot Stem**:
- The transverse section of a monocot stem consists of several layers. The outermost layer is the epidermis, followed by the hypodermis.

2. **Identify the Layers**:
- In monocots, the hypodermis is generally not differentiated into various layers like in dicots. In dicots, the hypodermis is divided into the cortical layer, hypodermis, and endodermis.

3. **Check for the Endodermis**:
- In monocots, the endodermis is absent. This is a significant difference from dicots, where the endodermis is present and serves as a starch sheath.

4. **Look for Other Structures**:
- Monocot stems have sclerenchymatous bundle sheaths surrounding the vascular bundles, and they also contain lysigenous cavities (water-filled cavities formed by the breakdown of cells).

5. **Conclusion**:
- The character that is not found in the transverse section of a monocot stem is the "starch sheath" (endodermis), which is present in dicots. Therefore, the correct answer is option four.

### Final Answer:
The character that is not found in the transverse section of a monocot stem is the **starch sheath (endodermis)**.
