How are bacteria classified?

Answer 1

Bacteria are classified in many ways. Most bacteria are classified by their shape, cell wall, movement, eating, and breathing.

The most useful technique of classification would be the Gram stain. The Gram stain distinguishes between differences in the cell wall composition of bacteria (Gram positive or Gram negative).

The shape of the bacteria could be spherical (coccus), rod (bacillus), spirochete, or vibrio (curved rod).

The texture could be wet/moist, dry, or mucoid. Bacteria come in a wide variety of colors.

Answer 2

Bacteria are classified according to their specific shape. There are rod, spiral, corkscrew, and spherical-shaped organisms. While rod-like bacteria are called bacilli, spherical-like bacteria are called cocci.

Answer 3

bacteria are classified because of their environment; and it complies naturally by the sense of contributing their cells.
