To what kingdom do common bacteria belong

A) Archaea B) Protista
C) Eubacteria D) All the above
 
Answer & Explanation Answer: C) Eubacteria

Explanation:

There are two kingdoms of bacteria. They are

1. Eubacteria  and 

2. Archaea

 

The members of these two kingdoms appear similar in shape and appearance, even under the extreme magnification of the electron microscope . However, they are very different from each other in a number of molecular and biochemical aspects. It is these differences that have resulted in the microorganisms being grouped into separate kingdoms.

 

For example, eubacteria contain the rigid, stress-bearing network known as the peptidoglycan . The only exceptions are the bacteria from the genera Mycoplasma and Chlamydia. Archaebacteria do not contain peptidoglycan. Instead, they contain a different structure that is called pseudomurein.

 

The common bacteria belongs to Eubacteria kingdom.
