Archaebacteria Examples

Archaebacteria are primitive, single-celled microorganisms that are prokaryotes with no cell nucleus. Each archaea has the ability to live in very severe environments.

Archaebacteria are one of the six kingdoms of life: plants, animals, protists, fungi, eubacteria and archaebacteria.
