2. **Identifying the Layers of Cortex**: The cortex consists of several layers. The outermost layer is known as the exodermis, which is followed by the hypodermis.

3. **Determining the Innermost Layer**: The innermost layer of the cortex is specifically referred to as the endodermis. This layer plays a crucial role in regulating the movement of water and nutrients into the vascular system of the plant.

4. **Conclusion**: Therefore, the innermost layer or last layer of the cortex is called the **endodermis**.
