Historically, archaea were referred to as archaebacteria and were categorized as bacteria. However, it was found that, in contrast to bacteria, archaea have a unique evolutionary history.
<h3>What are the differences between archaea and bacteria?</h3>
- A domain or kingdom of unicelled microbes is called the Archaea. Since these microorganisms are prokaryotes, their cells lack a cell nucleus and any other membrane-bound organelles. A significant portion of prokaryotic microorganisms are bacteria. Bacteria come in a variety of shapes, and are typically only a few micrometers long.
- Archaea live in extreme environments such as hot springs, gut of ruminants and humans, marshland etc. Bacteria are ubiquitous, they are found everywhere.
