Stele includes all of these except

Options

A. pericycle
B. vascular
C. pith
D. endodermis

Answer

To solve the question "Stele includes all of these except," we will analyze each of the options provided: pericycle, vascular tissue, pith, and endodermis.

### Step-by-step Solution:

1. **Understanding the Concept of Stele**:
- The stele is the central part of a root or stem. It consists of tissues derived from the procambium.

2. **Identifying Components of Stele**:
- The stele includes:
- **Vascular Tissues**: This includes xylem and phloem, which are responsible for the transport of water, nutrients, and food.
- **Pith**: This is the ground tissue located at the center of the stele.
- **Pericycle**: This is a layer of cells that can be found just inside the endodermis and can form lateral roots. It is not present in all plants but when it is, it forms the outermost boundary of the stele.

3. **Analyzing the Options**:
- **Pericycle**: Present in the stele.
- **Vascular Tissues**: Present in the stele.
- **Pith**: Present in the stele.
- **Endodermis**: This is located outside the stele and is the innermost layer of the cortex.

4. **Conclusion**:
- Since the endodermis is not part of the stele but rather located outside of it, the correct answer to the question is that the stele includes all of these except **endodermis**.

### Final Answer:
Stele includes all of these except **endodermis**.
