Cortex is the region found between:

Options

A. Endodermis and pith
B. Endodermis and vascular bundle
C. Epidermis and stele
D. Pericycle and endodermis

Answer

To answer the question "Cortex is the region found between:", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Cortex**: The cortex is a tissue layer found in plants, specifically in stems and roots. It is located between the outer layer and the inner vascular tissues.

2. **Identifying the Layers**:
- In stems, the cortex is situated between the epidermis (outer layer) and the vascular bundles (which contain xylem and phloem).
- In roots, the cortex is found between the epidermis and the endodermis (the innermost layer of the cortex that surrounds the vascular cylinder).

3. **Evaluating Options**:
- **Option 1: Endodermis and Pit**: The endodermis is an inner layer, and the pit is not a standard term for a layer adjacent to the cortex. This option is incorrect.
- **Option 2: Endodermis and Vascular Bundle**: The endodermis is indeed an inner layer, while the vascular bundle is also internal. This option does not correctly describe the position of the cortex.
- **Option 3: Epidermis and Stele**: The epidermis is the outermost layer, and the stele refers to the central part of the root or stem that includes vascular tissues. The cortex is located between the epidermis and the stele, making this option correct.
- **Option 4: Pericycle and Endodermis**: The pericycle is a layer found just inside the endodermis in roots, and thus does not include the cortex.

4. **Conclusion**: Therefore, the cortex is the region found between the epidermis and the stele.

### Final Answer:
Cortex is the region found between the epidermis and the stele.
