In addition, prokaryotic cells generally lack membrane-bound organelles. Prokaryotic cells of the same species typically share a similar cell morphology and cellular arrangement. Most prokaryotic cells have a cell wall that helps the organism maintain cellular morphology and protects it against changes in osmotic pressure.

This gives a surface area to volume ratio of 6:1. The surface area of the larger cell is 2mm x 2mm x 6 sides = 24mm 2 . The volume of the large cell is 2mm x 2mm x 2mm = 8mm 3 . This gives a surface area to volume ratio of 3:1 (24:8 reduces to 3:1).

Thus, the DNA for a cell must be packaged in a very ordered way to fit and function within a structure (the cell) that is not visible to the naked eye.
