Which structures that distinguish a eukaryotic cell from a prokaryotic cell are part of the internal membrane system?

The cell organelle that distinguishes the prokaryotic cell from the eukaryotic is the nucleus and other membrane bound organelles.

The nucleus is the genetic material that carries the traits from one generation to another.

This organelle is absent in prokaryotic cell and is only present in eukaryotic.

The other membrane bound organelles such as mitochondria, golgi body are also absent in prokaryotes.
