Rod-shaped bacteria are known as_:

Explanation

Rod-shaped bacteria are known as bacilli. They are one of the two main shapes of bacteria, the other being cocci (spherical bacteria). Bacilli are typically about 1-2 micrometers long and 0.5-1 micrometers wide. They can be found in a variety of environments, including soil, water, and the human body. Rod-shaped bacteria, also known as bacilli (singular: bacillus), are a common bacterial morphological form characterized by their elongated, cylindrical shape. These bacteria are typically longer than they are wide and may vary in length, from short rods to long filamentous forms. Rod-shaped bacteria can be found in a wide range of bacterial species and play various ecological and biological roles.
