Question

Give the characteristics of eubacteria.

Answer 1

Eubacteria:

1. Eubacteria are also known as “true bacteria”.
2. The cell wall is rigid and made up of peptidoglycans.
3. It moves with the help of flagella.
4. A few bacteria contain short appendages on the cell surface, known as pili which help the bacteria during sexual reproduction. Pili also helps a pathogen to attach to the host.
5. They are divided into two categories; gram-positive and gram-negative, depending upon the nature of the cell wall and the stain they take.
6. Rhizobium and Clostridium are two eubacteria.

Characteristics of eubacteria:

1. All bacteria are encased in a porous, but rigid cell wall that protects them from getting ruptured in watery environments and gives different characteristic shapes.
2. Mostly bacteria are motile containing one or more flagella. The flagella are made up of a protein called flagellin which has the ability to rotate.
3. These bacteria do not possess membrane-bounded organelles such as mitochondria, chloroplasts, etc.
