Which type of bacteria is typically spherical in shape?

Cocci refers to bacteria that are spherical in shape. These microorganisms can exist individually, in pairs, chains, or clusters, depending on their species and environmental conditions. The spherical form is one of the fundamental shapes classified in microbiology, reflecting a characteristic that can aid in the identification and study of different bacterial species.

In contrast, spirilla are bacteria that have a spiral or corkscrew shape, bacilli are rod-shaped, and vibrios have a curved or comma shape. Understanding these distinctions is crucial in the field of microbiology as the morphology of bacteria can play an important role in their classification, function, and the diseases they may cause.
