Question

What are bacteria give detail classification of bacteria with suteble example?

Answer 1

Classification of bacteria on the basis of shape: -

In the year 1872 scientist Cohn classified bacteria to 4 major types depending on their shapes are as follow: – 1) Cocci: These types of bacteria are unicellular, spherical or elliptical shape. Either they may remain as a single cell or may aggregate together for various configurations. They are as follow:

i) Monococcus: - they are also called micrococcus and represented by single, discrete round cell. Example: Micrococcus flavus. ii) Diplococcus: - the cell of the Diplococcus divides ones in a particular plane and after division, the cells remain attached to each other. Example: – Diplococcus pneumonia.

iii) Streptococcus: - here the cells divide repeatedly in one plane to form chain of cells. Example: – Streptococcus pyogenes.

Staphylococcus: - here the cells divided into three planes forming a structured like bunches of grapes giving and irregular configuration. Example: – Staphylococcus aureus.

Answer 2

Answer:

There are three basic bacterial shapes: Round bacteria called cocci (singular: coccus), cylindrical, capsule-shaped ones known as bacilli (singular: bacillus); and spiral bacteria, aptly called spirilla (singular: spirillum). The shapes and configurations of bacteria are often reflected in their names.
