Summary Introduction
To analyze:
The reasons why scientists are eager to explore about archaea have a hard time doing so.
Introduction:
Archaea constitute a domain of single celled microorganisms which are prokaryotes. They live under drastic conditions where no other life is possible. They are able to survive even in the absence of oxygen, high salt concentration and at high temperature or acidic pHs.
