What areProkaryotic all cell?

Prokaryotic cells are simple, unicellular organisms that lack a nucleus and membrane-bound organelles. They are characterized by their small size, typically ranging from 0.1 to 5 micrometers, and have a cell membrane, cell wall, and genetic material in the form of a single circular DNA molecule. Prokaryotes are divided into two main domains: Bacteria and Archaea. They play essential roles in various ecological processes, including nutrient cycling and decomposition.
