What are the classifications of bacteria by shape?

Bacteria are classified into five groups according to their basic shapes: spherical (cocci), rod (bacilli), spiral (spirilla), comma (vibrios) or corkscrew (spirochaetes). They can exist as single cells, in pairs, chains or clusters. Bacteria are found in every habitat on Earth: soil, rock, oceans and even arctic snow.

Which cell that is spherical in shape?

Answer: A coccus (plural cocci) is any bacterium or archaeon that has a spherical, ovoid, or generally round shape. Bacteria are categorized based on their shapes into three classes: cocci (spherical-shaped), bacillus (rod-shaped) and spirochetes (spiral-shaped) cells.

What kind of bacteria has a spherical shape?

Any bacteria or archaeon with an ovoid, spherical-shaped bacteria or usually round shaped bacteria is called a coccus (plural cocci). Bacteria are divided into three groups based on their coccus shape: bacillus (rod-shaped), cocci (spherical shaped bacteria), and spirochetes (spiral-shaped).

What is the genus and species of bacteria?
