A prokaryote is a single-celled organism that lacks a nucleus and other membrane-bound organelles.
Because they lack organelles that are attached to membranes, prokaryotes do not have an endomembrane system.
The endoplasmic reticulum (ER), Golgi complex, lysosomes, and vacuoles are components of the endomembrane system.
None of the organelles that make up the endomembrane system, excluding the plasma membrane, are present in prokaryotes.
The nucleus, the endoplasmic reticulum (ER), the Golgi apparatus, and lysosomes are only a few of the organelles or compartments that the endomembrane system separates into in a cell.
