Microorganisms are measured in:

Microorganisms are measured in:

• A. Millimeters
• B. Microns
• C. Nanometers
• D. Centimeters

Answer: (B)

Microorganisms, which include bacteria, viruses, fungi, and protozoa, are typically measured in microns (or micrometers). A micron is one-millionth of a meter, and this unit is particularly suitable for capturing the small size of most microbial life. For instance, many bacteria range from approximately 0.5 to 5 microns in size, making this measurement critical for understanding and studying their structure, behavior, and the methods used for disinfection and sterilization in medical settings. While nanometers (the size of some viruses) and millimeters (larger biomolecules or aggregates) are also relevant measurements in the biological sciences, they do not encompass the majority of microorganisms, which is why microns is the most appropriate choice for this context. Centimeters are too large a measurement to appropriately describe microorganisms, as even the largest bacteria would fall well below that scale.
