Which type of prokaryote morphology is described as spherical?

The description of prokaryote morphology as spherical specifically refers to cocci. Cocci are defined by their round shape, which can appear as single cells, in pairs (diplococci), in chains (streptococci), or in clusters (staphylococci). This spherical morphology is significant in microbiology because it can influence the way bacteria group together, how they interact with their environment, and their overall behavior.

Bacilli, on the other hand, are rod-shaped, spirilla are spiral-shaped, and vibrios are comma-shaped. Understanding these different shapes helps in the identification and classification of bacteria, which are crucial for studying their functions and roles in various environments, including human health.
