The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Structure**: The cortex is a layer found in both the roots and stems of flowering plants. It lies between the outer epidermis and the inner vascular bundles. 2. **Identifying the Layers**: In a transverse section of a root or stem, the outermost layer is the epidermis. Below the epidermis, there is a layer known as the cortex. 3. **Cortex Composition**: The cortex is primarily made up of parenchyma cells, which are living cells that are generally compact in nature. 4. **Innermost Layer of Cortex**: The innermost layer of the cortex is specifically known as the endodermis. This layer is crucial as it regulates the movement of water and nutrients into the vascular tissue. 5. **Evaluating Options**: - **Epidermis**: This is the outermost layer, so it cannot be the answer. - **Hypodermis**: This refers to the outer layer of the cortex, which is also not the answer. - **Pith**: This is located at the center of the stem and is not part of the cortex. - **Endodermis**: This is the correct answer as it is the innermost layer of the cortex. 6. **Conclusion**: The innermost layer of the cortex is the endodermis. ### Final Answer: The innermost layer of the cortex is the **endodermis**. ---
