Do bacteria move on its own?
Bacteria move around in many ways. Some bacteria move using flagella that they rotate to propel themselves through themselves through liquid environments. Other bacteria have a slimy layer on the outside that they use it slide over surfaces. Many types of bacteria do not have their own means of movement.
How do bacteria breathe move and reproduce?

Which is older bacteria or virus?
Viruses did not evolve first, they found. Instead, viruses and bacteria both descended from an ancient cellular life form. But while – like humans – bacteria evolved to become more complex, viruses became simpler. Today, viruses are so small and simple, they can’t even replicate on their own.

How fast do bacteria move?
Bacteria can reach speeds from 2 microns per second (Beggiatoa, a gliding bacteria) to 200 microns per second (Vibrio comma, polar bacteria). Speed varies with type of bacteria, but flagellates are undoubtedly faster than gliders.
