Answer

**Step-by-Step Solution:**

1. **Identify the Organisms**: The question refers to two species of tapeworms: Taenia saginata and Taenia solium.

2. **Understand the Key Features**: Both species belong to the same genus but have distinct anatomical features.

3. **Focus on the Head Structure**: The head of these tapeworms is called the scolex. It is essential to examine the structures present on the scolex of both species.

4. **Examine Taenia solium**: T. solium has both suckers and a unique hook-like structure on its scolex. The hooks are used for attachment to the host's intestinal wall.

5. **Examine Taenia saginata**: T. saginata, in contrast, has suckers but lacks the hook-like structures. This absence is a significant distinguishing feature between the two species.

6. **Conclusion**: The primary difference between Taenia saginata and Taenia solium is the absence of hooks on the scolex of T. saginata.

7. **Final Answer**: Taenia saginata differs from T. solium mainly in the absence of hooks on the scolex.
