What are bacteria?

Bacteria are single-celled organisms that can live in a wide variety of environments, including soil, water, and the bodies of plants and animals. They are prokaryotes, which means that they do not have a nucleus or other membrane-bound organelles.

Bacteria have a variety of shapes and sizes. Some bacteria are rod-shaped, while others are spherical or spiral-shaped. They can range in size from 1 to 10 micrometers in length.

Bacteria reproduce by binary fission, which means that they split in half to create two new bacteria. Bacteria can reproduce very quickly, and some species can double their population in as little as 20 minutes.

Are all bacteria dangerous?

No, not all bacteria are dangerous. In fact, most bacteria are actually beneficial and help us stay healthy.

For example, the bacteria in our gut help us digest food and fight off infections. The bacteria on our skin help to protect us from harmful bacteria and viruses.

Only a small number of bacteria are harmful and can cause diseases. These bacteria are called pathogens.

• Washing our hands frequently with soap and water
• Cooking food thoroughly
• Avoiding contact with sick people
