Bacteria exhibiting flagella scattered over the entire cell surface are termec:
1. lophotrichous
2. ambidextrous
3. peritrichous
4. amatrichous

The correct answer is 3. peritrichous

Explanation:

Flagella is the surface structure found in bacteria that helps in the locomotion of the bacteria. There can be single flagella that can be located at one end of the bacteria or many flagella present on all over the cell surface of the bacteria.

If a bacteria contains only one flagella at one end it is called monotonous. If many flagella are present at one end then it is called lophotrichous. When both the end of bacterial cell contains an equal amount of flagella then the bacteria is amphitrichous.

Peritrichous are those bacteria which contains many flagella that are located all over the surface of their body, for example, E. coli is the bacteria present in human intestine having flagella distributed all over its surface.
