A bacterium having one flagella each on the opposite ends is

Options

A. Monotrichous
B. Lophotrichous
C. Amphitrichous
D. Peritrichous.

Answer

To solve the question "A bacterium having one flagella each on the opposite ends is," we can follow these steps:

### Step-by-Step Solution:

1. **Understand Flagella Classification**: Bacteria can be classified based on the presence and arrangement of flagella. Flagella are tail-like structures that help bacteria in movement.

2. **Identify Types of Flagella Arrangement**:
- **Atrichous**: No flagella present; these bacteria are non-motile.
- **Monotrichous**: One flagellum at one end of the bacterium.
- **Lophotrichous**: A tuft of flagella at one end.
- **Peritrichous**: Flagella distributed all around the bacterium.
- **Amphitrichous**: One flagellum at each end of the bacterium.

3. **Analyze the Question**: The question specifically asks for a bacterium that has one flagellum at each of the opposite ends.

4. **Select the Correct Type**: From the types identified, the arrangement that fits the description of having one flagellum at each end is "Amphitrichous".

5. **Conclusion**: Therefore, the correct answer to the question is that the bacterium with one flagellum at each of the opposite ends is called "Amphitrichous".

### Final Answer:
The bacterium having one flagella each on the opposite ends is called **Amphitrichous**.
