Concept 7.2 Eukaryotic cells have internal membranes that compartmentalize their functions Prokaryotic and eukaryotic cells differ in size and complexity. All cells are surrounded by a  plasma membrane. The semifluid substance within the membrane is the  cytosol,  containing the organelles. All cells contain  chromosomes  that have genes in the form of DNA. All cells also have  ribosomes,  tiny organelles that make proteins using the instructions  contained in genes. A major difference between prokaryotic and eukaryotic cells is the location of chromosomes. In a eukaryotic cell, chromosomes are contained in a membrane-enclosed organelle, the  nucleus. In a  prokaryotic cell,  the DNA is concentrated in the  nucleoid  without a membrane  separating it from the rest of the cell. In  eukaryote cells,  the chromosomes are contained within a membranous nuclear  envelope.
