Halophilic prokaryote/halophile and Domain Archaea.


These are the clues that led to my answer.

No membranous organelles: Prokaryotes are known for this!

Cell wall lacks peptidoglycan:

This is common among eukaryotes and archaea. Since the organism is UNICELLULAR then it is not eukaryotes, so we are left with Archaea.


" grow well on 25% salt supplemented agar."

Halophile is an organism that thrives in saline conditions, so that means in HIGH SALT concentrations.
