Cortex is found in :

Options

A. stems only
B. roots only
C. roots and stems
D. roots, stems, and leaves

Explanation

**Step-by-Step Solution:**

1. **Understanding the Structure of a Plant:**
- The plant body is made up of different parts, including roots, stems, and leaves. Each part has specific tissues and functions.

2. **Identifying the Cortex:**
- The cortex is a layer of tissue found in the plant. It is located between the outer layer (epidermis) and the inner layer (endodermis) in roots and stems.

3. **Composition of the Cortex:**
- The cortex primarily consists of parenchyma cells, which are thin-walled and often involved in storage and transport functions.

4. **Function of the Cortex:**
- The cortex plays a role in the transportation of materials into the central cylinder of the root through diffusion. It can also serve as a storage site for food, particularly in the form of starch.

5. **Locating the Cortex in Plant Parts:**
- The cortex is present in both roots and stems, but not in leaves. Therefore, it is essential to identify where it is found.

6. **Conclusion:**
- Based on the information, the cortex is found in both roots and stems, making the correct answer option 3: "roots and stems."

**Final Answer:**
Cortex is found in roots and stems (Option 3).
