Outer most layer of stele in the root is

Options

A. Endodermis
B. Pericycle
C. Xylem bundles
D. Conjuctive tissue

Answer

To answer the question about the outermost layer of the stele in the root, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Root**: The root is composed of several layers, including the epidermis, cortex, endodermis, pericycle, and vascular tissues (xylem and phloem).

2. **Identify the Stele**: The stele refers to the central cylinder of the root that contains the vascular tissues (xylem and phloem) along with the pericycle.

3. **Locate the Outermost Layer of the Stele**: Within the stele, the pericycle is the outermost layer. It is situated just inside the endodermis.

4. **Describe the Pericycle**: The pericycle is typically made up of parenchyma or sclerenchyma cells and is cylindrical in structure. It plays a role in the growth of lateral roots and can also contribute to the formation of secondary growth in some plants.

5. **Conclude the Answer**: Therefore, the outermost layer of the stele in the root is the **pericycle**.

### Final Answer:
The outermost layer of the stele in the root is the **pericycle**.
