A single-celled creature without a nucleus and other membrane-bound organelles is known as a prokaryote.
Prokaryotes are divided into two distinct groups: bacteria and the archaea, which scientists believe have unique evolutionary lineages. Most prokaryotes are small, single-celled organisms
Basophilic bacteria:
Organisms that grow and replicate in very deep marine sediments are known as basophilic.
They are creatures that are similar to deep-sea bacteria or archaea, that live in high-pressure environments.
They show similarities with archaea which are prokaryotes, like them, basophilic organisms are also prokaryotes.
They are most commonly found on ocean floors, where the pressure is extraordinarily high, frequently exceeding 380 atm.
