Which root means 'bacteria'?

• A. Vas/o
• B. Glycos/o
• C. Azot/o
• D. Bacteri/o

Answer: (D)

Bacteria are what the word part refers to here. In medical terminology, bacteri/o designates bacteria, as seen in terms like bacteriology (the study of bacteria) and bacterium (a bacterial cell). The other roots point to different concepts: vas/o is vessel or vascular related, glycos/o relates to sugar, and azot/o concerns nitrogen. So the root that means bacteria is bacteri/o.
