The stele of a dicot stem includes all,except

Options

A. Vascular bundles
B. Pericycle
C. pith
D. Endodermis

Answer

To solve the question "The stele of a dicot stem includes all, except," we need to understand the components that make up the stele in a dicot stem.

### Step-by-Step Solution:

1. **Define the Stele**: The stele is the central part of a plant root or stem that contains the vascular tissues (xylem and phloem) and other associated tissues.

2. **Identify Components of a Dicot Stem**:
- The outermost layer is the **epidermis**.
- Below the epidermis, there may be a layer called the **hypodermis**.
- The next layer is the **cortex**, which lies between the epidermis and the endodermis.
- The **endodermis** is the innermost layer of the cortex.
- Inside the endodermis, there is the **pericycle**.
- The vascular tissues (xylem and phloem) are found within the **vascular bundles**.
- The innermost part of the stem is called the **pith**.

3. **Components of the Stele**:
- The stele includes the vascular tissues (xylem and phloem), the pericycle, and in some cases, the pith.
- The endodermis is not part of the stele; it is part of the cortex.

4. **Conclusion**: Based on the definitions and components identified, the answer to the question is that the **endodermis** is the component that is not included in the stele of a dicot stem.

### Final Answer:
The stele of a dicot stem includes all, except **endodermis**.
