The correct Answer is:
To answer the question "When a bacterial cell possesses a flagellum on its anterior and posterior sides, the condition is called," we will analyze the options provided and identify the correct term. ### Step-by-Step Solution: 1. **Understanding the Question**: The question asks about a specific arrangement of flagella on a bacterial cell. We need to identify the term that describes having flagella at both the anterior (front) and posterior (back) ends of the cell. 2. **Reviewing the Options**: - **Peritrichous**: This term refers to flagella that are distributed all over the surface of the bacterial cell. Since the question specifies flagella at the anterior and posterior ends only, this option is incorrect. - **Lophotrichous**: This term describes a tuft of flagella located at one end of the bacterial cell. Since this does not involve flagella at both ends, this option is also incorrect. - **Amphitrichous**: This term refers to a condition where one flagellum is present at the anterior end and another at the posterior end of the bacterial cell. This matches the condition described in the question. - **Monotrichous**: This term indicates the presence of a single flagellum at one end of the bacterial cell. Since the question specifies flagella at both ends, this option is incorrect. 3. **Identifying the Correct Answer**: Based on the analysis, the correct term for a bacterial cell that has a flagellum at both the anterior and posterior ends is **Amphitrichous**. 4. **Final Answer**: The condition is called **Amphitrichous**.
