Question

Describe the different shapes of bacteria.

Answer 1

Bacteria:

1. Bacteria belong to the kingdom monera.
2. Bacteria are microscopic.
3. Bacteria are unicellular, prokaryotes.
4. Bacteria can be autotrophic and can be heterotrophic.

Based on their shape bacteria are divided into several groups:

1. Cocci: These bacteria are spherical. They live as a single cell (monococcus), in a group of two (diplococcus), as a long-chain (streptococcus), or in bunches (staphylococcus). Examples: Streptococcus pneumoniae, Neisseria gonorrhoeae, etc.
2. Bacilli: Bacteria that are rod-shaped with or without flagella. They generally live as a single cell or in chains. Examples: Lactobacillus, Bacillus and Pseudomonas.
3. Spirilla: Spiral-shaped Bacteria. They live alone. They help increase the fertility of the soil. Example: Treponema, and Campylobacter.
4. Vibrio: Bacteria that are short, and curved like a common. Example: Vibrio cholerae.
