Fun Fact

Did you know that bacteria are among the oldest and most widespread forms of life on Earth? Most bacteria reproduce through a process called binary fission, where one bacterial cell divides into two. Some bacteria help us digest food, produce certain vitamins, and support healthy ecosystems. Others can cause infections and diseases. These tiny organisms play a huge role in our world, even though most are too small to see without a microscope!
