Q:3- Write detailed classification of bacteria for bacterial cell on the basis of its shape size and structure means morphology
Answers
Answer:
Cocci, Bacillus, Vibrio, Spirilla, Spirochete
Explanation:
Bacteria are single-celled and are classified under the domain Prokaryota. Although they are all microscopic organisms that can be found in various environments in nature, bacteria widely vary in size, shape, and arrangement.
Based on shape, bacteria can be classified as:
1.Cocci
Cocci bacteria appear spherical or oval in shape. Cocci may exist as single cells or remain attached to each other.
eg: Streptococcus pneumoniae
2.Bacillus
Bacillus bacteria are the rod-shaped bacteria. They are facultative anaerobes.
eg: Streptobacillus felis
3.Vibrio
Generally, vibrio bacteria are comma-shaped and thus not fully twisted (curved rods).
eg:Vibrio mytili
4.Spirilla
Spirilla are the helical shaped bacteria.
eg: Aquaspirillum
5.Spirochete
Spirochetes are also characterized by the helical shape. Spirochetes are also flexible and have been shown to produce mycelium. The movement involves the use of axial filaments.
eg: Leptospira
