Question:
Bacteria with group of flagella on both sides
Bacteria with group of flagella on both sides
Updated On: Jul 28, 2022
- amphitrichous
- cephalotrichous
- peritrichous
- lophotrichous
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
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 bacterial 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 'Amphitrichous.'

Biological Classification
The process of grouping living organisms into categories is called biological classification. The most modern 5-kingdom classification was put ahead by an eminent scientist R.H.Whittaker. The five-kingdom classification is based on the criteria like cell structure, mode of nutrition, body form, and reproduction. One of the most important characteristics of this system is that it follows the evolutionary sequence of living organisms. The organisms are classified into distinct taxa or levels like Kingdom, Phylum, Division, Class, Order, Family, Genus, and Species. The 5 kingdoms are as follows:
