Prokaryotes.
The "powerhouse" of a prokaryotic cell can be the cell membrane. That's where they produce their ATP.
Prokaryotes do not have a membrane-bound nucleus.
In eukaryotes respiration happens in the mitochondria and in prokaryotes the mechanisms of respiration are in the cell membrane as protons must be taken in through the membrane.
Well, the cell membrane is on the outside of a cell. So that is the answer , on the outside of the cell, protecting the inner part.
Prokaryotes.
cell membrane
prokaryotes
Prokaryotes do not have a membrane bound nucleus. The DNA is dispersed in a prokaryotic cell.
Prokaryotes and archea
yes it is found in prokaryotes as it has no membrane to cover it and the prokaryotic cell or prokaryotes lack just membrane bounded organelles and it performs the same function as in eukaryotes
Archaea do not have a cell membrane or any other membrane-bound organelles. They are also called prokaryotes.

Cell membrane
Prokaryotes do not have a membrane-bound nucleus.
Any cell with a nucleus will have a nuclear membrane. The nuclear membrane is just the outside of the nucleus - like the rubber on the outside of a rubber ball - that keeps your DNA in one place. Eukaryotes have nuclei, and therefore also have nuclear membranes. Prokaryotes (such as bacteria) do not have nuclei, and therefore don't have nuclear membranes. Their DNA floats free in the cell.
