Which of the following is not a character of Taenia solium ?

Options

A. Apolysis
B. Proglottid
C. Complete gut
D. Flame cells

Answer

To determine which of the following is not a characteristic of Taenia solium, we will analyze each option provided:

1. **Apolysis**: This refers to the process by which proglottids (segments of the body) are shed from the tapeworm. Taenia solium does exhibit apolysis as it sheds its proglottids.

2. **Proglottid**: Taenia solium is a type of tapeworm, and its body is segmented into numerous proglottids. Therefore, proglottids are indeed a characteristic of Taenia solium.

3. **Complete gut**: Taenia solium does not have a complete digestive system. Instead, it absorbs nutrients directly through its skin, which means it lacks a complete gut. This is a defining characteristic of tapeworms.

4. **Flame cell**: Flame cells are specialized excretory cells found in some invertebrates, including certain flatworms. Taenia solium does possess flame cells as part of its excretory system.

Based on this analysis, the option that is **not a characteristic of Taenia solium** is:

**Complete gut**.

### Step-by-Step Solution:
1. **Identify the options given**: Apolysis, Proglottid, Complete gut, Flame cell.
2. **Analyze each option**:
- Apolysis: Present in Taenia solium.
- Proglottid: Present in Taenia solium.
- Complete gut: Not present in Taenia solium.
- Flame cell: Present in Taenia solium.
3. **Determine which option is not a characteristic**: The complete gut is absent in Taenia solium.
4. **Conclude the answer**: The characteristic that is not present in Taenia solium is the complete gut.
