What are microscopic organisms?

Microscopic organisms are tiny living things you can’t see without special tools.

Imagine a world where there are little people who live in your hair or on your skin, they’re so small, you need a microscope to see them. That’s what microscopic organisms are like! They're all around us, and they come in many shapes and sizes.

Some microscopic organisms are like tiny helpers. For example, bacteria can be found on your hands or even inside your body, some help you digest food, while others might make you feel sick if they’re not friendly.

Other microscopic organisms are more like tiny visitors. Imagine little creatures swimming in a puddle or floating in the air, that’s what protists and fungi can be like. They're all part of the invisible world that lives right under our noses!
