Question

In peritrichous bacteria, flagella occur

• A. At one end
• B. At both ends
• C. All over the body
• D. Absent

Answer 1

The correct option is C All over the body

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 all over the bacterial cell.

Thus, the correct answer is 'All over the body.'
