That's a lot of cells! Bacteria are about the simplest cells that exist today. A bacteria is a single, self-contained, living cell. An Escherichia coli bacteria (or E. coli bacteria) is typical -- it is about one-hundredth the size of a human cell (maybe a micron long and one-...

How do cell parts work together? What are cells: Cells are the basic building blocks of life that make up all living organisms. Some organisms, like bacteria and protists, are single-celled, while others, such as plants and animals, are made of millions, or even trillions, of cells worki...
