🦠 Introduction to Microbiology

Meet the tiny living things all around us! Put each microbe under the microscope and find out if it's a friend or foe.

🧠 The Big Idea

Microorganisms are living things too small to see without a microscope — bacteria, viruses, fungi, protozoa & algae.
Many are helpful: they make curd & bread, medicines, and recycle waste. Some are harmful and cause disease.
Viruses are special — they can only multiply inside a living cell.
