Question

A bacterium with flagella all around is

• A. Amphitrichous
• B. Lophptrichous
• C. Cephalotrichous
• D. Peritrichous

Answer 1

The correct option is D Peritrichous

There are four types of flagellar arrangements based on the number and placement of flagella on the cell. These are,

1. Monotrichous - A single flagellum extends from one end of the cell.

2. Amphitrichous - A single flagellum or multiple flagella extend from two ends of the cell.

3. Lophotrichous - Tuft of flagella extend from one end or both ends of the cell.

4. Peritrichous - Multiple flagella randomly distributed over the entire bacterial cell.

Thus, the correct answer is 'Peritrichous.'
