Question

Bacteria containing a tuft of flagella that comes out from one pole is called___.

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

Answer 1

The Correct Option is A

In biological classification, bacteria can be categorized based on the arrangement of their flagella. These arrangements are significant for their mobility and adaptability in different environments.

Let's break down the options provided:

1. Lophotrichous: This term refers to bacteria that have a cluster of flagella at one or both ends. Hence, bacteria with a tuft of flagella at one pole are classified as lophotrichous. This is the correct answer.
2. Peritrichous: Bacteria with flagella distributed uniformly over the entire surface fall into this category. They are not limited to a single pole or end.
3. Monotrichous: Bacteria with a single flagellum usually located at one end of the bacterium fall under this category. This is distinct from having a tuft.
4. Amphitrichous: Bacteria with a single flagellum at each end of the cell are designated as amphitrichous.

Based on this classification, the correct answer to the question is Lophotrichous.
