What term describes rod-shaped bacteria?

Explanation:
Bacteria are classified by shape, and rod-shaped forms are called bacilli. The singular term bacillus describes a single rod-shaped bacterium, while bacilli refers to multiple rods. In contrast, cocci are spherical, and spirilla/spirochetes are spiral-shaped. Prefixes like diplo describe how bacteria are arranged (in pairs), not their shape. So bacillus is the term that describes rod-shaped bacteria.
