What is the difference between Fungi and Bacteria?

We find both fungus and bacteria everywhere, but do you really know the difference between those two? Today, let’s learn basics about them and compare the key differences.


  • Evolved more than 900 million years ago.

  • Multi-celled microorganisms.

  • Can grow on their own by obtaining energy from the existing environment.

  • Fungi could be used to make antibiotics such as Penicillin

  • Fungi can cause disease for animal and plants (ex. Athlete’s foot, fungal nail infection)


  • Evolved around 3-5 billion years ago.

  • Single-celled microorganisms.

  • Need a host to grow – bacteria need to get energy from sugars, proteins, and fats.

  • Bacteria can be used to decomposing organic matters (fermentation), and therefore it is used to make certain food such as yogurt and cheese.

  • Bacteria can also cause illness. (ex. tuberculosis, pneumonia, throat infection)

In conclusion, fungi and bacteria have a different history, different structures, and different ways to thrive. But they also have similarities such that they can both cause disease and infection, yet can be useful for certain purposes.
