🇬🇧 Microorganism meaning: English Vocabulary Flash Card

A microorganism is a living creature that is so tiny you cannot see it with just your eyes. You need a special tool called a microscope, which makes tiny things look big, to see it. Microorganisms can be bacteria, some types of fungi, or very small plants and animals that live almost everywhere—on your skin, in your mouth, in soil, in water, and even in your stomach. Some microorganisms help us, like the ones that help digest our food, and some can make us sick, so washing hands and keeping clean is important.
