3. **Characteristics of Casparian Strips**: Note that Casparian strips are hydrophobic, meaning they repel water. This characteristic is important as it helps regulate the movement of water and solutes into the vascular system of the plant.

4. **Structure of Endodermis**: Understand that the endodermis is the innermost layer of the cortex in roots. The cells of the endodermis are arranged in a ring-like structure.

5. **Conclusion**: Therefore, the answer to the question is that Casparian strips are present in the endodermis of the root.
