🦠 Unit of Measurement in Bacteriology

Let’s understand this in a very simple way.

What does bacteriology measure?
Bacteriology is the study of bacteria (very tiny organisms).

👉 So we need a unit to measure very small size.

Which unit is used?

✅ Correct Answer: (c) Micron

What is a micron?
A micron (μm) is a very small unit of length.

👉 1 micron = 1/1000 of a millimeter 👉 Used to measure size of bacteria and cells

Why other options are not correct?

• (a) Joule → ❌ Unit of energy
• (b) Newton → ❌ Unit of force
• (d) Pascal → ❌ Unit of pressure

Simple Exam Trick:
Bacteria = very small → Micron (μm)

📌 Note: Most bacteria range from about 0.5 to 5 microns in size.
