What shape describes cocci bacteria?

Cocci bacteria are characterized by their round-shaped appearance. This term is derived from the Greek word "kokkos," which means "berry," aptly describing their spherical form. Cocci can exist as single cells, in pairs, chains, or clusters, but they maintain that distinct round shape, which is one of the primary ways to classify bacteria morphologically. Understanding the shape of cocci is crucial in microbiology and can aid in identifying bacterial species and determining their potential impacts on health and disease.
