WebProkaryotic cells are smaller and simpler than eukaryotic cells, and do not have a nucleus. Prokaryote = "before carrier bag" i.e. without a nucleus Eukaryote = "good carrier bag" i.e. with a nucleus The close detail of a cell, with all organelles visible, that can be seen by using an electron microscope is refered to as the ultra-structure. WebThe outer membrane is visible as a 5–10 nm thick double-striped structure on the outer surface of the cell in electron microscopic thin sections. Scanning, negative smear, and thin-section electron microscopy techniques indicate that Gram-negative cells have a wavy exterior with numerous surface extrusions and intussusceptions.
