Cortex is the region found between

Options

A. epidermis and stele
B. pericycle and endodermis
C. endodermis and pith
D. endodermis and vascular bundle

Answer

**Step-by-Step Solution:**

1. **Understanding the Structure of a Plant:**
- In a typical cross-section of a root or stem, various layers can be identified. The outermost layer is known as the epidermis, which serves as a protective covering for the plant.

2. **Identifying the Cortex:**
- Beneath the epidermis, there is a region called the cortex. The cortex consists of parenchyma cells and is responsible for storage and transport of nutrients.

3. **Identifying the Endodermis:**
- Below the cortex, there is a layer known as the endodermis. The endodermis acts as a selective barrier that regulates the flow of water and nutrients into the vascular system.

4. **Understanding the Vascular System:**
- Following the endodermis, we find the pericycle, which is a layer of tissue that can give rise to lateral roots. Below the pericycle, the vascular bundles (xylem and phloem) are located, which are responsible for the transport of water, nutrients, and food.

5. **Identifying the Pith:**
- At the center of the root or stem, there is a region called the pith, which is primarily made up of parenchyma cells and serves as storage.

6. **Conclusion:**
- The cortex is specifically defined as the region found between the epidermis and the stele (the central vascular tissue). Therefore, the correct answer to the question is that the cortex is the region found between the epidermis and the stele.

**Final Answer:**
The cortex is the region found between the epidermis and the stele.
